146-496: Cheating in video games involves a video game player using various methods to create an advantage beyond normal gameplay , usually in order to make the game easier. Cheats may be activated from within the game itself (a cheat code implemented by the original game developers), or created by third-party software (a game trainer or debugger) or hardware (a cheat cartridge ). They can also be realized by exploiting software bugs ; this may or may not be considered cheating based on whether

292-616: A ban . However, certain games may unlock single-player cheats if the player fulfills a certain condition. Yet other games, such as those using the Source engine , allow developer consoles to be used to activate a wide variety of cheats in single-player or by server administrators. Many games which use in-game purchases consider cheating to be not only wrong but also illegal, seeing as cheats in such games would allow players to access content (like power-ups and extra coins) that would otherwise require payment to obtain. However, cheating in such games

438-408: A computer game or just a game , is an electronic game that involves interaction with a user interface or input device (such as a joystick , controller , keyboard , or motion sensing device) to generate visual feedback from a display device , most commonly shown in a video format on a television set , computer monitor , flat-panel display or touchscreen on handheld devices , or

584-457: A teletype printer , audio speaker , or similar device. This also distinguished from many handheld electronic games like Merlin which commonly used LED lights for indicators but did not use these in combination for imaging purposes. "Computer game" may also be used as a descriptor, as all these types of games essentially require the use of a computer processor, and in some cases, it is used interchangeably with "video game". Particularly in

730-638: A virtual reality headset . These games are addictive and can lead to the release of dopamine in the addict's synapses. Most modern video games are audiovisual , with audio complement delivered through speakers or headphones , and sometimes also with other types of sensory feedback (e.g., haptic technology that provides tactile sensations). Some video games also allow microphone and webcam inputs for in-game chatting and livestreaming . Video games are typically categorized according to their hardware platform , which traditionally includes arcade video games , console games , and computer (PC) games ;

876-549: A DEC PDP-1 computer in 1962. Each game has different means of display: NIMROD has a panel of lights to play the game of Nim , OXO has a graphical display to play tic-tac-toe, Tennis for Two has an oscilloscope to display a side view of a tennis court, and Spacewar! has the DEC PDP-1's vector display to have two spaceships battle each other. These inventions laid the foundation for modern video games. In 1966, while working at Sanders Associates , Ralph H. Baer devised

1022-566: A blind-eye to such trading as detection and prevention requires resources and banning players also results in losses of revenue. Cheating in online games is common on public game servers . Some online games, such as Battlefield 1942 , include specific features to counter cheating exploits , by incorporating tools such as PunkBuster , nProtect GameGuard , or Valve Anti-Cheat . However, much like anti-virus companies, some anti-cheat tools are constantly and consistently bypassed until further updates force cheat creators to find new methods to bypass

1168-549: A car with greater acceleration, or just visual gags such as "big-head mode" in GoldenEye 007 . Some games humorously penalise the player for using another game's cheat codes. For example, using cheat codes from Doom in Heretic gives the opposite of the desired effect, such as instant death instead of invulnerability or stripping weapons instead of providing them. Unlike other cheating methods, cheat codes are implemented by

1314-407: A certain sequence. Less common activation methods include entering certain high score names, holding keys or buttons while dying, picking up items in a particular order and otherwise performing unintuitive actions. Some games may also offer a debug console that can be used to edit game parameters. Effects might include unlocking a character or improving a character's performance: for example providing

1460-437: A combination of the limitations of the game platform and display device and the program efficiency of the game itself. The game's output can range from fixed displays using LED or LCD elements, text-based games , two-dimensional and three-dimensional graphics, and augmented reality displays. The game's graphics are often accompanied by sound produced by internal speakers on the game platform or external speakers attached to

1606-449: A common type of video game hacking is through the use of DLLs . Users use a third party program to inject the DLL into their game of choice. Editing a saved game offers an indirect way to modify game data. By modifying a file in persistent storage, it is possible to effectively modify the runtime game data that will be restored when the game attempts to load the save game. Hex editors were

1752-401: A common use for lagswitches was the ability to understand enemy positions without any risk to the player. For example, if a player was unsure whether an enemy was present in a room, they could activate the lag switch to block network traffic momentarily. This would allow the player to enter the room and scout for enemies without their movements being transmitted to the game server. As a result,

1898-445: A developer's programming language of choice, or they may opt to also use game development kits that minimize the amount of direct programming they have to do but can also limit the amount of customization they can add into a game. Like all software, video games usually undergo quality testing before release to assure there are no bugs or glitches in the product, though frequently developers will release patches and updates . With

2044-410: A displacement allowing for more natural shapes such as hills to be created. Scenery objects or complex geometry can be imported as separate 3D models from the game directory. These models can also be used as physics objects or interactive props. The editor also features an in-depth logic I/O system that can be used to create complex interactive elements. Signals to trigger different responses or change

2190-414: A fictional piece of technology from Star Trek , arguing for the video game as a medium in which the player is allowed to become another person, and to act out in another world. This image of video games received early widespread popular support, and forms the basis of films such as Tron , eXistenZ and The Last Starfighter . Ludologists break sharply and radically from this idea. They argue that

2336-494: A framework on top of SRCDS for custom modification of gameplay on existing titles. Source Filmmaker (SFM) is a 3D animation application that was built from within the Source engine. Developed by Valve, the tool was originally used to create movies for Day of Defeat: Source and Team Fortress 2 . It was also used to create some trailers for Source Engine games. SFM was released to the public in 2012. In June 2016, Valve released

2482-523: A full upgrade of the Source engine for the release of The Orange Box . An artist-driven, threaded particle system replaced previously hard-coded effects for all of the games within. An in- process tools framework was created to support it, which also supported the initial builds of Source Filmmaker . In addition, the facial animation system was made hardware-accelerated on modern video cards for "feature film and broadcast television" quality. The release of The Orange Box on multiple platforms allowed for

2628-432: A game following its initial release. Several games offer players the ability to create user-generated content to share with others to play. Other games, mostly those on personal computers, can be extended with user-created modifications or mods that alter or add onto the game; these often are unofficial and were developed by players from reverse engineering of the game, but other games provide official support for modding

2774-614: A home computer or console. It allows a user to modify the game code either before or during its execution. An early example is the Multiface for the ZX Spectrum, and almost every format since has had a cheat cartridge created for it; such as Datel 's range of Action Replay devices. Another popular example of this is Game Genie for Genesis , NES , Super NES , Game Boy , and Game Gear game consoles. Modern disc-based cheat hardware includes GameShark and Code Breaker which modify

2920-506: A large code refactoring , which let the Source engine take advantage of multiple CPU cores. However, support on the PC was experimental and unstable until the release of Left 4 Dead . Multiprocessor support was later backported to Team Fortress 2 and Day of Defeat: Source . Valve created the Xbox 360 release of The Orange Box in-house, and support for the console is fully integrated into

3066-415: A letter dated July 10, 1972. In the letter, Bushnell uses the term "video game" twice. Per video game historian Keith Smith, the sudden appearance suggested that the term had been proposed and readily adopted by those in the field. Around March 1973, Ed Adlum, who ran Cashbox ' s coin-operated section until 1972 and then later founded RePlay Magazine , covering the coin-op amusement field, in 1975, used

3212-504: A limited number of platforms, and exclusivity to a platform or brand is used by platform holders as a competitive edge in the video game market. However, games may be developed for alternative platforms than intended, which are described as ports or conversions. These also may be remasters - where most of the original game's source code is reused and art assets, models, and game levels are updated for modern systems – and remakes, where in addition to asset improvements, significant reworking of

3358-432: A minimum age is used by nearly all systems, along with additional descriptors to identify specific content that players and parents should be aware of. The regulations vary from country to country but generally are voluntary systems upheld by vendor practices, with penalty and fines issued by the ratings body on the video game publisher for misuse of the ratings. Among the major content rating systems include: Additionally,

3504-407: A non-cheating player. Notable examples include the following: Cheating exists in many multiplayer video games . While there have always been cheat codes and other ways to make single-player games easier, developers often attempt to prevent it in multiplayer games. With the release of the first popular internet multiplayer games, cheating took on new dimensions. Previously it was rather easy to see if

3650-551: A platform, the hardware which contains computing elements, to process player interaction from some type of input device and displays the results to a video output display. Video games require a platform, a specific combination of electronic components or computer hardware and associated software , to operate. The term system is also commonly used. These platforms may include multiple brandsheld by platform holders , such as Nintendo or Sony, seeking to gain larger market shares. Games are typically designed to be played on one or

3796-469: A relatively recent development in the humanities. The two most visible schools in this emerging field are ludology and narratology . Narrativists approach video games in the context of what Janet Murray calls "Cyberdrama". That is to say, their major concern is with video games as a storytelling medium, one that arises out of interactive fiction . Murray puts video games in the context of the Holodeck ,

3942-455: A service . Today, video game development requires numerous interdisciplinary skills, vision , teamwork , and liaisons between different parties, including developers , publishers , distributors , retailers , hardware manufacturers, and other marketers, to successfully bring a game to its consumers. As of 2020 , the global video game market had estimated annual revenues of US$ 159 billion across hardware, software, and services, which

4088-595: A similar version running in a smaller coin-operated arcade cabinet using a less expensive computer. This was released as Computer Space , the first arcade video game , in 1971. Bushnell and Dabney went on to form Atari, Inc. , and with Allan Alcorn , created their second arcade game in 1972, the hit ping pong -style Pong , which was directly inspired by the table tennis game on the Odyssey. Sanders and Magnavox sued Atari for infringement of Baer's patents, but Atari settled out of court, paying for perpetual rights to

4234-411: A single + and a number appended to their title, representing the number of modifications the trainer has available. In the 1980s and 1990s, trainers were generally integrated straight into the actual game by cracking groups . When the game was first started, the trainer would typically show a splash screen of its own, sometimes allowing modifications of options related to the trainer, and then proceed to

4380-443: A small part of the game before launching it. In the context of games for many 8-bit computers, it was a usual practice to load games into memory and, before launching them, modify specific memory addresses in order to cheat, getting an unlimited number of lives, currency, immunity, invisibility, etc. Such modifications were performed through POKE statements. The Commodore 64 , Amstrad CPC range and ZX Spectrum also allowed players with

4526-571: A step further and allow the player to export and import data edits. Edit templates of many games for a console are collected and redistributed as cheat packs. Emulators also frequently offer the additional advantage of being able to save the state of the entire emulated machine at any point, effectively allowing saving at any point in a game even when save functionality is not provided by the game itself. Cheating hardware such as "Instant Replay" also allows such behavior for some consoles. Somewhat more unusual than memory editing, code injection consists of

4672-523: A system to play a basic table tennis game on a television screen. With the company's approval, Baer created the prototype known as the "Brown Box." Sanders patented Baer’s innovations and licensed them to Magnavox , which commercialized the technology as the first home video game console , the Magnavox Odyssey , released in 1972. Separately, Nolan Bushnell and Ted Dabney , inspired by seeing Spacewar! running at Stanford University , devised

4818-430: A variety of different purposes, including development. Developers may use the program to view models and their corresponding animations, attachment points, bones, and so on. Face Poser is the tool used to access facial animations and choreography systems. This tool allows one to edit facial expressions , gestures and movements for characters, lip sync speech, and sequence expressions and other acting cues and preview what

4964-424: A video game are primarily determined by the underlying set of rules, demands, and expectations imposed on the player. While many games rely on emergent principles , video games commonly present simulated story worlds where emergent behavior occurs within the context of the game. The term "emergent narrative" has been used to describe how, in a simulated environment, storyline can be created simply by "what happens to

5110-412: A video game is first and foremost a game, which must be understood in terms of its rules, interface, and the concept of play that it deploys. Espen J. Aarseth argues that, although games certainly have plots, characters, and aspects of traditional narratives, these aspects are incidental to gameplay. For example, Aarseth is critical of the widespread attention that narrativists have given to the heroine of

5256-457: A way to distinguish them from console games , arcade games , or mobile games . Other terms such as "television game", "telegame", or "TV game" had been used in the 1970s and early 1980s, particularly for home gaming consoles that rely on connection to a television set . However, these terms were also used interchangeably with "video game" in the 1970s, primarily due to "video" and "television" being synonymous. In Japan , where consoles like

5402-411: A word from Billboard ' s description of movie jukeboxes, Adlum started to refer to this new breed of amusement machine as 'video games.' The phrase stuck." Adlum explained in 1985 that up until the early 1970s, amusement arcades typically had non-video arcade games such as pinball machines and electro-mechanical games . With the arrival of video games in arcades during the early 1970s, there

5548-431: Is a video game "appears highly eclectic and diverse". The gameplay experience varies radically between video games, but many common elements exist. Most games will launch into a title screen and give the player a chance to review options such as the number of players before starting a game. Most games are divided into levels which the player must work the avatar through, scoring points , collecting power-ups to boost

5694-479: Is an overhaul of many aspects of the Source engine through the development of the Left 4 Dead series . Multiprocessor support was further expanded, allowing for features like split screen multiplayer, additional post-processing effects, event scripting with Squirrel , and the highly-dynamic AI Director . The menu interface was re-implemented with a new layout designed to be more console-oriented. This branch later fueled

5840-459: Is frequently a cross-disciplinary field. Video game developers , as employees within this industry are commonly referred to, primarily include programmers and graphic designers . Over the years, this has expanded to include almost every type of skill that one might see prevalent in the creation of any movie or television program, including sound designers , musicians, and other technicians; as well as skills that are specific to video games, such as

5986-421: Is from 1947—a " cathode-ray tube amusement device " was filed for a patent on 25 January 1947, by Thomas T. Goldsmith Jr. and Estle Ray Mann, and issued on 14 December 1948, as U.S. Patent 2455992. Inspired by radar display technology, it consists of an analog device allowing a user to control the parabolic arc of a dot on the screen to simulate a missile being fired at targets, which are paper drawings fixed to

6132-431: Is lost. More modern methods typically involve lower level packet editing or forgery in a " Man-in-the-middle attack " style. For example, symmetric encryption keys could be read from the game's memory, granting access to inbound packets. These packets could be edited to provide the client game with information that does not reflect the server's reality. I.e. if an enemy player uses an ability that should slow your movement,

6278-562: Is mostly isolated from the rest of the world due to the government's censorship, and all games published there must adhere to strict government review, disallowing content such as smearing the image of the Chinese Communist Party . Foreign games published in China often require modification by developers and publishers to meet these requirements. Video game development and authorship, much like any other form of entertainment,

6424-553: Is nonetheless a legal grey area because there are no laws against modifying software which is already owned, as detailed in the Digital Millennium Copyright Act. The most basic type of cheat code is one created by the game designers and hidden within the video game itself, that will cause any type of uncommon effect that is not part of the usual game mechanics. Cheat codes are usually activated by typing secret passwords or pressing controller buttons in

6570-422: Is really difficult, right? I never played it that much, and there was no way I could finish the game, so I inserted the so-called Konami Code." A bot is a type of artificial intelligence (AI)–based expert system software that plays a video game in the place of a human, to perform actions (repetitive or not) that enable advantages to be achieved. Cheating can easily be achieved by modifying the game's data while it

6716-412: Is running. These methods of cheating are often less reliable than cheat codes included in a game by its creators. This is due to the fact that certain programming styles or quirks of internal game logic, different release versions of a game, or even using the same game at different times or on different hardware, may result in different memory usage and hence the trainer program might have no effect, or stop

6862-447: Is the primary means which one interacts with a video game. The narrative setting does not impact gameplay; a shooter game is still a shooter game, regardless of whether it takes place in a fantasy world or in outer space. An exception is the horror game genre, used for games that are based on narrative elements of horror fiction , the supernatural , and psychological horror . Genre names are normally self-describing in terms of

7008-571: Is three times the size of the global music industry and four times that of the film industry in 2019, making it a formidable heavyweight across the modern entertainment industry . The video game market is also a major influence behind the electronics industry , where personal computer component, console, and peripheral sales, as well as consumer demands for better game performance, have been powerful driving factors for hardware design and innovation. Early video games use interactive electronic devices with various display formats. The earliest example

7154-530: The Berne Convention . This typically only applies to the underlying code, as well as to the artistic aspects of the game such as its writing, art assets, and music. Gameplay itself is generally not considered copyrightable; in the United States among other countries, video games are considered to fall into the idea–expression distinction in that it is how the game is presented and expressed to

7300-646: The Clue VCR Mystery Game which required players to watch VCR clips between turns. To distinguish between these two, video games are considered to require some interactivity that affects the visual display. Most video games tend to feature some type of victory or winning conditions, such as a scoring mechanism or a final boss fight. The introduction of walking simulators ( adventure games that allow for exploration but lack any objectives) like Gone Home , and empathy games (video games that tend to focus on emotion) like That Dragon, Cancer brought

7446-483: The Game Genie , created derivative works of games and thus violated copyright law. The most basic way of achieving this is by means of memory editor software, which allows the player to directly edit the numeric values in a certain memory address. This kind of software usually includes a feature that allows the player to perform memory searches to aid the user to locate the memory areas where known values (such as

7592-555: The United Kingdom and Western Europe , this is common due to the historic relevance of domestically produced microcomputers. Other terms used include digital game, for example, by the Australian Bureau of Statistics . However, the term "computer game" can also be used to more specifically refer to games played primarily on personal computers or other types of flexible hardware systems (also known as PC game ), as

7738-500: The Unterhaltungssoftware Selbstkontrolle ( Entertainment Software Self-Regulation ) would refuse to classify, and thus allow sale, of any game depicting Nazi imagery, and thus often requiring developers to replace such imagery with fictional ones. This ruling was relaxed in 2018 to allow for such imagery for "social adequacy" purposes that applied to other works of art. China's video game segment

7884-449: The backward compatibility -breaking "version jumps" of its competitors. Different systems within Source are represented by separate modules which can be updated independently. With Steam , Valve can distribute these updates automatically among its many users. In practice, however, there have been occasional breaks in this chain of compatibility. The release of Half-Life 2: Episode One and The Orange Box both introduced new versions of

8030-483: The crash of the North American video game market in 1983 due to loss of publishing control and saturation of the market. Following the crash, the industry matured, was dominated by Japanese companies such as Nintendo , Sega , and Sony , and established practices and methods around the development and distribution of video games to prevent a similar crash in the future, many of which continue to be followed. In

8176-619: The first-person shooter and the Grand Theft Auto clone , respectively, in the few years after their release. However, at times and more frequently at the onset of the industry, developers would intentionally create video game clones of successful games and game hardware with few changes, which led to the flooded arcade and dedicated home console market around 1978. Cloning is also a major issue with countries that do not have strong intellectual property protection laws, such as within China . The lax oversight by China's government and

8322-409: The game designer . All of these are managed by producers . In the early days of the industry, it was more common for a single person to manage all of the roles needed to create a video game. As platforms have become more complex and powerful in the type of material they can present, larger teams have been needed to generate all of the art, programming, cinematography, and more. This is not to say that

8468-452: The wallhack , which allows a player to see through solid or opaque objects or manipulate or remove textures, meshing , which is the action of pushing an item/npc/player into the graphic boundary of another object/player/location in a manner not intended by the game developer, and ESP , with which the information of other players is displayed. There are also cheats that increase the size of the target's hitbox , allowing shots striking close to

8614-439: The 1950s and 1960s were simple extensions of electronic games using video-like output from large, room-sized mainframe computers . The first consumer video game was the arcade video game Computer Space in 1971. In 1972 came the iconic hit game Pong and the first home console , the Magnavox Odyssey . The industry grew quickly during the "golden age" of arcade video games from the late 1970s to early 1980s but suffered from

8760-526: The 1970s and 1980s before having a larger worldwide contribution. Today, the video game industry is predominantly led by major companies in North America (primarily the United States and Canada), Europe, and southeast Asia including Japan, South Korea, and China. Hardware production remains an area dominated by Asian companies either directly involved in hardware design or part of the production process, but digital distribution and indie game development of

8906-527: The 1983 crash, forming around the concept of publisher-developer dichotomies, and by the 2000s, leading to the industry centralizing around low-risk, triple-A games and studios with large development budgets of at least $ 10 million or more. The advent of the Internet brought digital distribution as a viable means to distribute games, and contributed to the growth of more riskier, experimental independent game development as an alternative to triple-A games in

9052-462: The 1993 game . A hierarchy of game genres exist, with top-level genres like "shooter game" and "action game" that broadly capture the game's main gameplay style, and several subgenres of specific implementation, such as within the shooter game first-person shooter and third-person shooter . Some cross-genre types also exist that fall until multiple top-level genres such as action-adventure game . A video game's mode describes how many players can use

9198-631: The 2000s, the core industry centered on " AAA " games, leaving little room for riskier experimental games. Coupled with the availability of the Internet and digital distribution , this gave room for independent video game development (or " indie games ") to gain prominence into the 2010s. Since then, the commercial importance of the video game industry has been increasing. The emerging Asian markets and proliferation of smartphone games in particular are altering player demographics towards casual gaming and increasing monetization by incorporating games as

9344-822: The Destinations Workshop Tools, a set of free virtual reality (VR) creation tools running using the Source 2 SDK. In June 2005, Valve opened the Valve Developer Community wiki . It replaced Valve's static Source SDK documentation with a full MediaWiki -powered community site. Valve staff have occasionally produced professional and/or academic papers for various events and publications, including SIGGRAPH , Game Developer Magazine and Game Developers Conference , explaining various aspects of Source engine's development. Titanfall , Titanfall 2 , and Apex Legends are not included because their engines, while originally based on

9490-602: The Goldsrc branch of code referred to the codebase that was currently released, and Src referred to the next set of more risky technology that we were working on. When it came down to show Half-Life 2 for the first time at E3 , it was part of our internal communication to refer to the "Source" engine vs. the "Goldsource" engine, and the name stuck. Source was developed part-by-part from this fork onwards, slowly replacing GoldSrc in Valve's internal projects and, in part, explaining

9636-637: The Internet or other communication methods as well as cloud gaming alleviate the need for any physical media. In some cases, the media serves as the direct read-only memory for the game, or it may be the form of installation media that is used to write the main assets to the player's platform's local storage for faster loading periods and later updates. Games can be extended with new content and software patches through either expansion packs which are typically available as physical media, or as downloadable content nominally available via digital distribution. These can be offered freely or can be used to monetize

9782-539: The Mad Overlord ' s 1981 release, at least two commercial trainers appeared. 1983 advertisements for "The Great Escape Utility" for Castle Wolfenstein (1981) promised that the $ 15 product "remodels every feature of the game. Stop startup delays, crashes and chest waiting. Get any item, in any quantity. Start in any room, at any rank. Handicap your aim. Even add items". In a computer game, all numerical values are stored "as is" in memory. Gamers could reprogram

9928-467: The Odyssey were first imported and then made within the country by the large television manufacturers such as Toshiba and Sharp Corporation , such games are known as "TV games", "TV geemu", or "terebi geemu". The term "TV game" is still commonly used into the 21st century. "Electronic game" may also be used to refer to video games, but this also incorporates devices like early handheld electronic games that lack any video output. The first appearance of

10074-416: The ZX Spectrum, immunity is achieved. Magazines such as Crash regularly featured lists of such POKE instructions for games. In order to find them a hacker had to interpret the machine code and locate the critical point where the number of lives is decreased, impacts detected, etc. Sometimes the term POKE was used with this specific meaning. Cheating was exploited by technology-oriented players due to

10220-485: The actual game. In the cracker group release lists and intros, trained games were marked with one or more plus signs after them, one for each option in the trainer, for example: "the Mega Krew presents: Ms. Astro Chicken++ ". Many emulators have built-in functionality that allows players to modify data as the game is running, sometimes even emulating cheating hardware such as Game Genie . Some emulators take this method

10366-728: The age of the "one-man shop" is gone, as this is still sometimes found in the casual gaming and handheld markets, where smaller games are prevalent due to technical limitations such as limited RAM or lack of dedicated 3D graphics rendering capabilities on the target platform (e.g., some PDAs ). Video games are programmed like any other piece of computer software. Prior to the mid-1970s, arcade and home consoles were programmed by assembling discrete electro-mechanical components on circuit boards, which limited games to relatively simple logic. By 1975, low-cost microprocessors were available at volume to be used for video game hardware, which allowed game developers to program more detailed games, widening

10512-475: The asset pipeline, as well as a few GUI-based programs designed for handling more complex functions. Source SDK was launched as a free standalone toolset through Steam, and required a Source game to be purchased on the same account. Since the release of Left 4 Dead in late 2008, Valve began releasing "Authoring Tools" for individual games, which constitute the same programs adapted for each game's engine build. After Team Fortress 2 became free-to-play, Source SDK

10658-417: The avatar's innate attributes, all while either using special attacks to defeat enemies or moves to avoid them. This information is relayed to the player through a type of on-screen user interface such as a heads-up display atop the rendering of the game itself. Taking damage will deplete their avatar's health , and if that falls to zero or if the avatar otherwise falls into an impossible-to-escape location,

10804-476: The bug is considered common knowledge. The first cheat codes were put in place for play testing purposes. Playtesters had to rigorously test the mechanics of a game and introduced cheat codes to make this process easier. An early cheat code can be found in Manic Miner , where typing "6031769" (based on Matthew Smith's driving license) enables the cheat mode. Within months of Wizardry: Proving Grounds of

10950-434: The cars in front of them and the obstacle. The programmer never wrote code to specifically create a traffic jam, yet one now exists in the game. Most commonly, video games are protected by copyright , though both patents and trademarks have been used as well. Though local copyright regulations vary to the degree of protection, video games qualify as copyrighted visual-audio works, and enjoy cross-country protection under

11096-417: The console itself, while peripheral controllers are available as a separate purchase from the console manufacturer or third-party vendors. Similar control sets are built into handheld consoles and onto arcade cabinets. Newer technology improvements have incorporated additional technology into the controller or the game platform, such as touchscreens and motion detection sensors that give more options for how

11242-423: The difficulty for foreign companies to take Chinese entities to court had enabled China to support a large grey market of cloned hardware and software systems. The industry remains challenged to distinguish between creating new games based on refinements of past successful games to create a new type of gameplay, and intentionally creating a clone of a game that may simply swap out art assets. The early history of

11388-419: The difficulty of early cheats. However, a cheat industry emerged as gaming systems evolved, through the packaging and selling of cheating as a product. Cheat-enablers such as cheat books, game guides, cheat cartridges helped form a cheat industry and cemented cheating as part of gaming culture. However, cheating was not universally accepted in early gaming; gaming magazine Amiga Power condemned cheaters, taking

11534-569: The engine during its lifetime. Source was succeeded in 2015 by the release of Source 2 . Source distantly originates from the GoldSrc engine, itself a heavily modified version of John Carmack 's Quake engine with some code from the Quake II engine . Carmack commented on his blog in 2004 that "there are still bits of early Quake code in Half-Life 2 ". Valve employee Erik Johnson explained

11680-488: The engine that could not be used to run older games or mods without the developers performing upgrades to code and, in some cases, content. Both cases required markedly less work to update its version than competing engines. The Source 2006 branch was the term used for Valve's games using technology that culminated with the release of Half-Life 2: Episode One . HDR rendering and color correction were first implemented in 2005 using Day of Defeat: Source , which required

11826-631: The engine's nomenclature on the Valve Developer Community: When we were getting very close to releasing Half-Life (less than a week or so), we found there were already some projects that we needed to start working on, but we couldn't risk checking in code to the shipping version of the game. At that point we forked off the code in VSS to be both /$ Goldsrc and /$ Src . Over the next few years, we used these terms internally as "Goldsource" and "Source". At least initially,

11972-632: The engine's shaders to be rewritten. The former, along with developer commentary tracks, were showcased in Half-Life 2: Lost Coast . Episode One introduced Phong shading and other smaller features. Image-based rendering technology had been in development for Half-Life 2 , but was cut from the engine before its release. It was mentioned again by Gabe Newell in 2006 as a piece of technology he would like to add to Source to implement support for much larger scenes that are impossible with strictly polygonal objects. The Source 2007 branch represented

12118-434: The game Tomb Raider , saying that "the dimensions of Lara Croft 's body, already analyzed to death by film theorists , are irrelevant to me as a player, because a different-looking body would not make me play differently... When I play, I don't even see her body, but see through it and past it." Simply put, ludologists reject traditional theories of art because they claim that the artistic and socially relevant qualities of

12264-642: The game at the same type. This is primarily distinguished by single-player video games and multiplayer video games . Within the latter category, multiplayer games can be played in a variety of ways, including locally at the same device, on separate devices connected through a local network such as LAN parties , or online via separate Internet connections. Most multiplayer games are based on competitive gameplay, but many offer cooperative and team-based options as well as asymmetric gameplay . Online games use server structures that can also enable massively multiplayer online games (MMOs) to support hundreds of players at

12410-406: The game can also be exploited. On some consoles, cheat cartridges allow players to execute these cheat codes, and user-developed trainers allow similar bypassing for computer software games. Both of which might make the game easier, give the player additional power-ups, or change the appearance of the game. To distinguish from electronic games, a video game is generally considered to require

12556-481: The game code from a large database of cheats. In later generation consoles, cheat cartridges have come to be replaced by cheat discs, containing a simple loader program which loads a game disc and modifies the main executable before starting it. The legality of this type of devices has been questioned, such as in the case of Lewis Galoob Toys, Inc. v. Nintendo of America, Inc. , in which Nintendo unsuccessfully sued Lewis Galoob Toys stating that its cheating device,

12702-554: The game developers themselves, often as a tool to playtest certain aspects of the game without difficulty. One of the earliest known examples of this type of cheat is the Konami Code , created in 1986 by Konami developer Kazuhisa Hashimoto as he worked on porting the 1985 arcade game Gradius for use on the Nintendo Entertainment System . Hashimoto is quoted as saying "The arcade version of Gradius

12848-423: The game from running altogether. Modifying game data usually constitutes a violation of a software license agreement that prohibits modifying the program at all. Cheating via memory editing involves modifying the memory values where the game keeps its status information. The way to achieve this will vary depending on the environment in which the game is running. A cheat cartridge is attached to an interface port on

12994-484: The game should they lose all their lives or need to stop the game and restart at a later time. These also may be in the form of a passage that can be written down and reentered at the title screen. Product flaws include software bugs which can manifest as glitches which may be exploited by the player; this is often the foundation of speedrunning a video game. These bugs, along with cheat codes , Easter eggs , and other hidden secrets that were intentionally added to

13140-501: The game. Video game can use several types of input devices to translate human actions to a game. Most common are the use of game controllers like gamepads and joysticks for most consoles, and as accessories for personal computer systems along keyboard and mouse controls. Common controls on the most recent controllers include face buttons, shoulder triggers, analog sticks , and directional pads ("d-pads") . Consoles typically include standard controllers which are shipped or bundled with

13286-399: The game. By definition, all video games are intended to output graphics to an external video display, such as cathode-ray tube televisions, newer liquid-crystal display (LCD) televisions and built-in screens, projectors or computer monitors , depending on the type of platform the game is played on. Features such as color depth , refresh rate , frame rate , and screen resolution are

13432-560: The game. Today, many games are built around a game engine that handles the bulk of the game's logic, gameplay, and rendering. These engines can be augmented with specialized engines for specific features, such as a physics engine that simulates the physics of objects in real-time. A variety of middleware exists to help developers access other features, such as playback of videos within games, network-oriented code for games that communicate via online services, matchmaking for online games, and similar features. These features can be used from

13578-485: The growth of the size of development teams in the industry, the problem of cost has increased. Development studios need the best talent, while publishers reduce costs to maintain profitability on their investment. Typically, a video game console development team ranges from 5 to 50 people, and some exceed 100. In May 2009, Assassin's Creed II was reported to have a development staff of 450. The growth of team size combined with greater pressure to get completed projects into

13724-586: The idea of games that did not have any such type of winning condition and raising the question of whether these were actually games. These are still commonly justified as video games as they provide a game world that the player can interact with by some means. The lack of any industry definition for a video game by 2021 was an issue during the case Epic Games v. Apple which dealt with video games offered on Apple's iOS App Store . Among concerns raised were games like Fortnite Creative and Roblox which created metaverses of interactive experiences, and whether

13870-506: The item. An alternative method for cheating in online games involves modification of inbound or outbound network traffic between the client and server. One early implementation of this concept was seen with lag switches. A lag switch refers to any hardware or software mechanism that temporarily limits network traffic. They grew popular as, unlike most cheats, they could be used on the Xbox One and PS4 consoles. In first-person shooters ,

14016-451: The items in a treasure chest, while another represents the player's inventory, then the player can save the game before and after picking up an item from the chest, and continue play using the treasure chest file before the item was picked up, and the inventory file from afterward -- allowing the player to pick up the item repeatedly, gaining multiple instances of the item, if the program's logic does not prevent them from having more than one of

14162-450: The larger " AAA " game studios, and are often experiments in gameplay and art style. Indie game development is aided by the larger availability of digital distribution, including the newer mobile gaming market, and readily-available and low-cost development tools for these platforms. Although departments of computer science have been studying the technical aspects of video games for years, theories that examine games as an artistic medium are

14308-718: The larger game and the individual experiences themselves were games or not in relation to fees that Apple charged for the App Store. Judge Yvonne Gonzalez Rogers , recognizing that there was yet an industry standard definition for a video game, established for her ruling that "At a bare minimum, video games appear to require some level of interactivity or involvement between the player and the medium" compared to passive entertainment like film, music, and television, and "videogames are also generally graphically rendered or animated, as opposed to being recorded live or via motion capture as in films or television". Rogers still concluded that what

14454-417: The late 2000s and which has continued to grow as a significant portion of the video game industry. Video games have a large network effect that draw on many different sectors that tie into the larger video game industry. While video game developers are a significant portion of the industry, other key participants in the market include: The industry itself grew out from both the United States and Japan in

14600-502: The late 2000s has allowed game developers to flourish nearly anywhere and diversify the field. Source (game engine) Source is a 3D game engine developed by Valve . It debuted as the successor to GoldSrc in 2004 with the releases of Half-Life: Source , Counter-Strike: Source , and Half-Life 2 . Other notable third-party games using Source include Vampire: The Masquerade – Bloodlines , Dear Esther , and The Stanley Parable . Valve released incremental updates to

14746-452: The latter also encompasses LAN games , online games , and browser games . More recently, the video game industry has expanded onto mobile gaming through mobile devices (such as smartphones and tablet computers ), virtual and augmented reality systems, and remote cloud gaming . Video games are also classified into a wide range of genres based on their style of gameplay and target audience . The first video game prototypes in

14892-424: The main engine codeline. It includes asset converters, cross-platform play and Xbox Live integration. Program code can be ported from PC to Xbox 360 simply by recompiling it. The PlayStation 3 release was outsourced to Electronic Arts , and was plagued with issues throughout the process. Gabe Newell cited these issues when criticizing the console during the release of The Orange Box . The Left 4 Dead branch

15038-682: The major content system provides have worked to create the International Age Rating Coalition (IARC), a means to streamline and align the content ratings system between different region, so that a publisher would only need to complete the content ratings review for one provider, and use the IARC transition to affirm the content rating for all other regions. Certain nations have even more restrictive rules related to political or ideological content. Within Germany, until 2018,

15184-431: The majority of cheat codes on modern day systems are implemented not by gamers, but by game developers . Some say that as many people do not have the time to complete a video game on their own, cheats are needed to make a game more accessible and appealing to a casual gamer. In many cases, developers created cheats to facilitate testing, then left them in the game as they expanded the number of ways people could play it. With

15330-462: The market to begin recouping production costs has led to a greater occurrence of missed deadlines, rushed games, and the release of unfinished products. While amateur and hobbyist game programming had existed since the late 1970s with the introduction of home computers, a newer trend since the mid-2000s is indie game development . Indie games are made by small teams outside any direct publisher control, their games being smaller in scope than those from

15476-405: The market. Due to loss of publishing control and oversaturation of the market, the North American home video game market crashed in 1983 , dropping from revenues of around $ 3 billion in 1983 to $ 100 million by 1985. Many of the North American companies created in the prior years closed down. Japan's growing game industry was briefly shocked by this crash but had sufficient longevity to withstand

15622-415: The modification of the game's executable code while it is running, for example with the use of POKE commands. In the case of Jet Set Willy on the ZX Spectrum computer, a popular cheat involved replacing a Z80 instruction DEC (HL) in the program (which was responsible for decrementing the number of lives by one) with a NOP , effectively granting the player infinite lives. On Microsoft Windows ,

15768-518: The most basic means of editing saved game files (e.g. to give the player a large sum of money in strategy games such as Dune II ). However, as happened with game editors, dedicated game-editing utilities soon became available, including functions to effortlessly edit saved data for specific games, rendering hex editing largely obsolete for this purpose. If a saved game is stored in multiple files, it may also be possible to cheat simply by mixing and matching these files. For example, if one file represents

15914-420: The number of lives, score or health level) are located. Provided a memory address, a memory editor may also be able to "freeze" it, preventing the game from altering the information stored at that memory address. Game trainers are a special type of memory editor, in which the program comes with predefined functions to modify the run time memory of a specific computer game . When distributed, trainers often have

16060-774: The original game and possibly from scratch is performed. The list below is not exhaustive and excludes other electronic devices capable of playing video games such as PDAs and graphing calculators . Early arcade games, home consoles, and handheld games were dedicated hardware units with the game's logic built into the electronic componentry of the hardware. Since then, most video game platforms are considered programmable, having means to read and play multiple games distributed on different types of media or formats. Physical formats include ROM cartridges , magnetic storage including magnetic-tape data storage and floppy discs , optical media formats including CD-ROM and DVDs , and flash memory cards. Furthermore digital distribution over

16206-412: The other players cheated, as most games were played on local networks or consoles. The Internet changed that by increasing the popularity of multiplayer games, giving the players relative anonymity, and giving people an avenue to communicate cheats. Examples of cheats in first-person shooter games include the aimbot , which assists the player in aiming at the target, giving the user an unfair advantage,

16352-495: The packet detailing the slow factor could be modified to a lower value, manipulating the client game into applying the lower value. Techniques like this are not as common as simple memory manipulation and are typically only used in specific scenarios. In games having attainable achievements or high score records, or both, cheats by nature allow the player to attain achievements too easily or score point totals not attainable or extremely difficult to attain through legitimate means by

16498-472: The patents. Following their agreement, Atari made a home version of Pong , which was released by Christmas 1975. The success of the Odyssey and Pong , both as an arcade game and home machine, launched the video game industry. Both Baer and Bushnell have been titled "Father of Video Games" for their contributions. The term "video game" was developed to distinguish this class of electronic games that were played on some type of video display rather than on

16644-409: The platform, as directed by the game's programming. This often will include sound effects tied to the player's actions to provide audio feedback, as well as background music for the game. Some platforms support additional feedback mechanics to the player that a game can take advantage of. This is most commonly haptic technology built into the game controller, such as causing the controller to shake in

16790-399: The player interacts with the game. Specialized controllers may be used for certain genres of games, including racing wheels , light guns and dance pads . Digital cameras and motion detection can capture movements of the player as input into the game, which can, in some cases, effectively eliminate the control, and on other systems such as virtual reality, are used to enhance immersion into

16936-502: The player that can be copyrighted, but not the underlying principles of the game. Because gameplay is normally ineligible for copyright, gameplay ideas in popular games are often replicated and built upon in other games. At times, this repurposing of gameplay can be seen as beneficial and a fundamental part of how the industry has grown by building on the ideas of others. For example Doom (1993) and Grand Theft Auto III (2001) introduced gameplay that created popular new game genres,

17082-433: The player will lose one of their lives . Should they lose all their lives without gaining an extra life or "1-UP" , then the player will reach the " game over " screen. Many levels as well as the game's finale end with a type of boss character the player must defeat to continue on. In some games, intermediate points between levels will offer save points where the player can create a saved game on storage media to restart

17228-419: The player's hands to simulate a shaking earthquake occurring in game. Video games are frequently classified by a number of factors related to how one plays them. A video game, like most other forms of media, may be categorized into genres . However, unlike film or television which use visual or narrative elements, video games are generally categorized into genres based on their gameplay interaction, since this

17374-430: The player." However, emergent behavior is not limited to sophisticated games. In general, any place where event-driven instructions occur for AI in a game, emergent behavior will exist. For instance, take a racing game in which cars are programmed to avoid crashing, and they encounter an obstacle in the track: the cars might then maneuver to avoid the obstacle causing the cars behind them to slow or maneuver to accommodate

17520-422: The player’s character technically remained in the safe position from the server’s (and enemy's) perspective. Once the player had gathered the necessary information about enemy locations, they could deactivate the lag switch and resume normal play. Many games have since implemented "anti-desync" measures to limit the effectiveness of lagswitches. This may include the client game preventing player movement if connection

17666-628: The process of porting, Valve rearranged most of the games released up to The Orange Box into separate, but parallel "singleplayer" and "multiplayer" branches. The game code to these branches was made public to mod developers in 2013, and they serve as the current stable release of Source designated for mods. Support for Valve's internal Steam Pipe distribution system as well as the Oculus Rift are included. In May 2014, Nvidia released ports of Portal and Half-Life 2 to their Tegra 4 -based Android handheld game console Nvidia Shield . Source 2

17812-535: The proper cartridges or Multiface add-on to freeze the running program, enter POKEs, and resume. Some games tried to detect the Multiface and refused to load if it was present. The earliest models had no ability to "hide". Later revisions either included a switch, hid if the menu had been opened and closed before loading the game, or automatically hid. For instance, with POKE 47196,201 in Knight Lore for

17958-577: The protection. In single-player games, there are a number of plug-ins available to developers to use to stop cheaters. An obfuscator will scramble code so it is unreadable by decompilers, rename events/properties/methods and even add fake code. An obscurer will encrypt variables in memory and mask out strings. Anti-cheat toolkits have a variety of tools such as: detecting speed hacks, encrypting player prefs, detecting time cheats, detecting wall hacks and more. These can be used in most multi-player games as well. Video game A video game , also known as

18104-450: The question of what are the essential factors of a video game that separate the medium from other forms of entertainment. The introduction of interactive films in the 1980s with games like Dragon's Lair , featured games with full motion video played off a form of media but only limited user interaction. This had required a means to distinguish these games from more traditional board games that happen to also use external media, such as

18250-435: The reasons behind its unusually modular nature. Valve's development of Source since has been a mixture of licensed middleware and in-house-developed code. Older versions of Source use Bink Video for video playback, however more recent releases of the Source engine use WebM videos for menu backgrounds, Full Motion Videos , and splash screens. . Source was created to evolve incrementally with new technology, as opposed to

18396-647: The release of the Steam client on the same platform. Valve announced that all their future games would be released simultaneously for Windows and Mac. The first of Valve's games to support Linux was Team Fortress 2 , the port released in October 2012 along with the closed beta of the Linux version of Steam. Both the OS X and Linux ports of the engine take advantage of OpenGL and are powered by Simple DirectMedia Layer . During

18542-464: The releases of Alien Swarm and Portal 2 , the former released with source code outlining many of the changes made since the branch began. Portal 2 , in addition, served as the result of Valve taking the problem of porting to PlayStation 3 in-house, and in combination with Steamworks integration creating what they called "the best console version of the game". In April 2010, Valve released all of their major Source games on OS X , coinciding with

18688-434: The rise in popularity of gaming, cheating using external software and hardware raised a number of copyright legal issues related to modifying game code. Many modern games have removed cheat codes entirely, except when used to unlock certain secret bonuses. The usage of real-time achievement tracking made it unfair for any one player to cheat. In online multiplayer games, cheating is frowned upon and disallowed, often leading to

18834-637: The same time. A small number of video games are zero-player games , in which the player has very limited interaction with the game itself. These are most commonly simulation games where the player may establish a starting state and then let the game proceed on its own, watching the results as a passive observer, such as with many computerized simulations of Conway's Game of Life . Most video games are intended for entertainment purposes. Different game types include: Video games can be subject to national and international content rating requirements. Like with film content ratings, video game ratings typing identify

18980-499: The scene will look like in the game engine. The Hammer Editor, the engine's official level editor , uses rendering and compiling tools included in the SDK to create maps using the binary space partitioning (BSP) method. Level geometry is created with 3D polygons called brushes ; each face can be assigned a texture which also defines the properties of the surface such as the sounds used for footsteps. Faces can also be converted into

19126-544: The scope of what was possible. Ongoing improvements in computer hardware technology have expanded what has become possible to create in video games, coupled with convergence of common hardware between console, computer, and arcade platforms to simplify the development process. Today, game developers have a number of commercial and open source tools available for use to make games, often which are across multiple platforms to support portability, or may still opt to create their own for more specialized features and direct control of

19272-617: The screen. Other early examples include Christopher Strachey 's draughts game, the Nimrod computer at the 1951 Festival of Britain ; OXO , a tic-tac-toe computer game by Alexander S. Douglas for the EDSAC in 1952; Tennis for Two , an electronic interactive game engineered by William Higinbotham in 1958; and Spacewar! , written by Massachusetts Institute of Technology students Martin Graetz, Steve Russell , and Wayne Wiitanen's on

19418-435: The short-term effects, and Nintendo helped to revitalize the industry with the release of the Nintendo Entertainment System in North America in 1985. Along with it, Nintendo established a number of core industrial practices to prevent unlicensed game development and control game distribution on their platform, methods that continue to be used by console manufacturers today. The industry remained more conservative following

19564-521: The stance that cheating was not part of their philosophy of fairness. They also applied this in reverse; games should also not be allowed to cheat the player. Guides, walkthroughs, and tutorials are sometimes used to complete games but whether this is cheating is debated. Later, cheating grew more popular with magazines, websites, and even a television show, Cheat! , dedicated to listing cheats and walkthroughs for consoles and computer systems. POKE cheats were replaced by trainers and cheat codes. Generally,

19710-455: The state of an entity can be sent between entities such as buttons, NPCs , intangible trigger brushes, and map props. The Source Dedicated Server (SRCDS) is a standalone launcher for the Source engine that runs multiplayer game sessions without requiring a client. It can be launched through Windows or Linux and can allow for custom levels and assets. Most third-party servers additionally run Metamod :Source and SourceMod, which together provide

19856-484: The target age group that the national or regional ratings board believes is appropriate for the player, ranging from all-ages, to a teenager-or-older, to mature, to the infrequent adult-only games. Most content review is based on the level of violence, both in the type of violence and how graphic it may be represented, and sexual content, but other themes such as drug and alcohol use and gambling that can influence children may also be identified. A primary identifier based on

20002-513: The target to register as hits. In online trading card games, creating multiple accounts by jailbreaking a device to get more rewards can be considered as cheating because it is unfair to players who have only one account. In online multiplayer games , a player may use macro scripts , which automatically find items or defeat enemies. The prevalence of massively multiplayer online games (MMORPGs) such as World of Warcraft , Anarchy Online , EverQuest , Guild Wars , and RuneScape has resulted in

20148-405: The term "video game" emerged around 1973. The Oxford English Dictionary cited a 10 November 1973 BusinessWeek article as the first printed use of the term. Though Bushnell believed the term came from a vending magazine review of Computer Space in 1971, a review of the major vending magazines Vending Times and Cashbox showed that the term may have come even earlier, appearing first in

20294-554: The term in an article in March 1973. In a September 1982 issue of RePlay , Adlum is credited with first naming these games as "video games": "RePlay's Eddie Adlum worked at 'Cash Box' when 'TV games' first came out. The personalities in those days were Bushnell, his sales manager Pat Karns, and a handful of other 'TV game' manufacturers like Henry Leyser and the McEwan brothers. It seemed awkward to call their products 'TV games', so borrowing

20440-498: The trading of in-game currency for real-world currency. This can lead to virtual economies . The rise of virtual economies has led to cheating where a gamer uses macros to gain large amounts of in-game money which the player will then trade for real cash. The Terms of Service of most modern online games now specifically prohibit the transfer of accounts or the sale of in-game items for 'real-world' money. The enforcement of these terms varies however from one company to another, many turning

20586-503: The type of gameplay, such as action game , role playing game , or shoot 'em up , though some genres have derivations from influential works that have defined that genre, such as roguelikes from Rogue , Grand Theft Auto clones from Grand Theft Auto III , and battle royale games from the film Battle Royale . The names may shift over time as players, developers and the media come up with new terms; for example, first-person shooters were originally called "Doom clones" based on

20732-422: The video game industry, following the first game hardware releases and through 1983, had little structure. Video games quickly took off during the golden age of arcade video games from the late 1970s to early 1980s, but the newfound industry was mainly composed of game developers with little business experience. This led to numerous companies forming simply to create clones of popular games to try to capitalize on

20878-576: Was announced by Valve as the successor to Source at the Game Developers Conference in March 2015. There, Valve stated that it would be free to use for developers, with support for the Vulkan graphical API , as well as using a new in-house physics engine called Rubikon. In June 2015, Valve announced that Dota 2 , originally made in the Source engine, would be ported over to Source 2 in an update called Dota 2 Reborn . Reborn

21024-488: Was effectively made open to all Steam users. When some Source games were updated to Source 2013, the older Source SDKs were phased out. The three applications mentioned below are now included in the install of each game. There are three applications packaged in the Source SDK: Hammer Editor, Model Viewer, and Face Poser. The Model Viewer is a program that allows users to view models and can be used for

21170-528: Was first released to the public as an opt-in beta update that same month before officially replacing the original client in September 2015, making it the first game to use the engine. The engine had succeeded Source by the late 2010s. Source SDK is the software development kit for the Source engine, and contains many of the tools used by Valve to develop assets for their games. It comes with several command-line programs designed for special functions within

21316-434: Was initially some confusion in the arcade industry over what term should be used to describe the new games. He "wrestled with descriptions of this type of game," alternating between "TV game" and "television game" but "finally woke up one day" and said, "What the hell... video game!" While many games readily fall into a clear, well-understood definition of video games, new genres and innovations in game development have raised
