The d20 System is a role-playing game system published in 2000 by Wizards of the Coast , originally developed for the 3rd edition of Dungeons & Dragons . The system is named after the 20-sided dice which are central to the core mechanics of many actions in the game.
91-657: Basic Role-Playing ( BRP ) is a tabletop role-playing game which originated in the RuneQuest fantasy role-playing game . Chaosium released the BRP standalone booklet in 1980 in the boxed set release of the second edition of RuneQuest . Greg Stafford and Lynn Willis are credited as the authors. Chaosium used the percentile skill-based system as the basis for most of their games, including Call of Cthulhu , Stormbringer , and Elfquest . The core rules were written by Steve Perrin as part of his game RuneQuest . It

Preexisting RPG and fiction settings converted to the system by Chaosium using the BRP ruleset include Ringworld , Hawkmoon , and an adaptation of the French RPG Nephilim . BRP is similar to other generic systems such as GURPS , Hero System , or Savage Worlds in that it uses a simple resolution method which can be broadly applied. It uses
273-763: A "skill" in one game may be a "talent" or "ability" in another. Attributes are statistics all characters possess: strength, agility, and intelligence are common examples. These are ranked, often on a numeric scale, so that a player can gauge the character's capabilities. For example, a character's strength rating could be used to determine the likelihood that the character can lift a certain weight. Skills are abilities that only some characters possess, such as negotiation, horseback riding, and marksmanship. Game systems often define skills that are genre-appropriate. For example, fantasy settings generally include magic skills, while science-fiction settings may contain spaceship piloting skills. However, some skills are found in several genres:
364-407: A character. This can take one of several forms: Characters in role-playing games are usually represented by a number of statistics . Statistics are an abstract measure of how successful a character is likely to be at a class of tasks. Many game systems make distinctions between two key types of statistic: attributes and skills . These names are not always consistent across different games -
455-415: A core set of seven characteristics : Size, Strength, Dexterity, Constitution, Intelligence, Power, and Appearance or Charisma. From these, a character derives scores in various skills , expressed as percentages. These skill scores are the basis of play. When attempting an action, the player rolls percentile dice to attempt to get a result equal to or lower than the character's skill score. Each incarnation of

Tabletop RPG settings includes challenges for the player characters to overcome through play, such as traps to be avoided, rulers to be courted, or adversaries to be fought.

Frequently, this involves interacting with non-player characters , other denizens of the game world, which are played by

The exact tone, structure, pace and end (if any) vary from game to game depending on

BRP was conceived of as a generic system. Specific rule systems for support differing genres could be added to the core rules in a modular fashion. In order to underscore this, in 1982 Chaosium released the Worlds of Wonder box set, which contained

Though role-playing has been generally accepted in society, the subject retains a level of controversy among some religious organizations. This belief or attitude is by no means universal among religious organizations; there are faith-based role-playing games on the market and religious role-players who disagree that these games are morally corrupt or occult in nature. Competition from role-playing video games and collectible card games led to

In 2004, Chaosium began publishing the Basic Roleplaying monographs, a series of paperback booklets. The first four monographs ( Players Book , Magic Book , Creatures Book , and Gamemaster Book )
1547-510: A setting can vary. Campaign settings such as the World of Greyhawk and Invisible Sun detail entire cosmologies and time-lines of thousands of years, while the setting of games such as Deadlands or Coyote & Crow might only describe one or more nations within a brief segment of alternate history . Other settings describe smaller locations, such as Blades in the Dark , which describes

Some settings involve shifting between multiple different planets or timelines, sometimes with their own genres. For instance, in GURPS Infinite Worlds , the characters are "Infinity Patrol" agents who travel to alternate worlds , some of which include fantasy or steampunk as well as science fiction elements. A number of campaign settings have fused multiple genres into

Meanwhile, Feng Shui combined Chinese historical fantasy with Kung Fu action tropes and dystopian science fiction. Instead of literary genres, some campaign settings are modeled on video game genres, such as Fabula Ultima , which

Guided by a developer/manager, freelancers produce most of a game line's content according to a central plan. Some start with already established franchises while others create original series and then branch out as a franchise to multiple medias. Finally, a few companies (such as Wizards of the Coast and Mongoose Publishing ) maintain an in-house writing and design staff. The standard business model for successful RPGs relies on multiple sales avenues: Typically, RPG publishers have

Independent or "indie" role-playing games are tabletop role-playing games produced by individual creators or small press publishers, in contrast to games published by large corporations . As a movement, indie game design typically emphasizes creative freedom and fair financial compensation for game designers. The indie role-playing game community often produces games with signature and idiosyncratic character. Some indie designers create and sell their own games on Itch.io , DriveThruRPG , Kickstarter , BackerKit , or via in-person sales at gaming conventions, while others use distribution services such as Indie Press Revolution .

There are alternate game systems which are diceless , or use alternate forms of randomization, such as
6734-431: The rules of the game. Tabletop role-playing games have origins in wargaming , which has roots in ancient strategy games , particularly chess and its predecessor Chaturanga . From the late 18th century to the 19th century, chess variants evolved into modern wargames, most notably Kriegsspiel . Over a century later, David Wesely developed Braunstein , the first tabletop roleplaying game, from Strategos , and then
6825-401: The setting and the GM's common sense; most actions are straightforward and immediately successful. For example, if a player has their character look around a room, the GM will describe the room; if they have their character leave, the GM will describe whatever they encounter outside the room. The outcomes of some actions are determined by the rules of the game. For example, while looking around
6916-440: The settings from d20 Modern into the full Urban Arcana Campaign Setting (2003) sourcebook, and further extending the d20 into science-fiction with d20 Future (2004) and into historical settings with d20 Past (2005), then finished up their d20 line in 2006 with the classic Dark•Matter campaign setting. Third-party publishers used these d20 genre books to base their own campaign settings on, such as White Wolf using
7007-457: The success of the market leader, which at that time was Wizards of the Coast . Dancey also theorized that the proliferation of numerous game systems actually made the role-playing game industry weaker, and these beliefs together led Dancey to the idea to allow other publishers to create their own Dungeons & Dragons supplements. This led to a pair of licenses that Wizards of the Coast released in 2000, before 3rd edition Dungeons & Dragons
7098-429: The system without paying for the use of the system's associated intellectual property, which is owned by Wizards of the Coast. The original impetus for the open licensing of the d20 System involved the economics of producing role-playing games (RPGs). Game supplements suffered far more diminished sales over time than the core books required to play the game. Ryan Dancey , brand manager for Dungeons & Dragons at
7189-550: The time, directed the effort of licensing the new edition of Dungeons & Dragons through the d20 System Trademark , allowing other companies to support the d20 System under a common brand identity. This is distinct from the Open Game License, which simply allows any party to produce works composed of or derivative of designated Open Game Content. The d20 System is a derivative of the third edition Dungeons & Dragons game system. The three primary designers behind
7280-464: The update and therefore many companies were stuck with books that were out-of-date before even reaching their audience. Wizards did not make any 3.5 update available for the d20 trademark. Between these two crises, many d20 publishers went out of business or left the field, but most that remained totally abandoned the d20 trademark in favor of publishing under the OGL. Publishers realized that they could publish d20 games successfully without depending upon
7371-501: Was Traveller , designed by Marc Miller and first published in 1977 by Game Designer's Workshop . This was originally intended to be a system for playing generic space-opera-themed science-fiction adventures (in the same sense that Dungeons & Dragons was a system for generic fantasy adventures), but an optional setting called "the Third Imperium " that was detailed in subsequent supplements became strongly identified with
7462-399: Was Greg Stafford 's idea to simplify the rules (eliminating such mechanics as Strike Ranks and Hit Locations) and issue them in a 16-page booklet called Basic Role-Playing . Since the first BRP release, designers including Sandy Petersen , Lynn Willis , and Steve Henderson , have contributed to the system. The system was notable for being the first role-playing game system to introduce
7553-472: Was a "sophisticated, intricate and complicated combat simulation board game that people were turning into a roleplaying game" just "like giving your rook a motive" in Chess. The assumption of roles was a central theme in some early 20th century activities such as the game Jury Box , mock trials, model legislatures, and "Theatre Games". In the 1960s, historical reenactment groups such as The Sealed Knot and
7644-559: Was also used as the base for the Swedish game Drakar och Demoner from Target Games . In the July 1981 edition of The Space Gamer (Issue No. 41), Ronald Pehr commented that " Basic Role-Playing is too little too late. RuneQuest is long established, does an adequate job of teaching role-playing, and there are now even more games to choose from. If you want to teach role-playing to a very young, but literate, child, Basic Role-Playing
7735-872: Was also used in Justice, Inc. (1984), Fantasy Hero (1985) and other games. Steve Jackson Games followed with GURPS (the Generic Universal Roleplaying System) in 1986. At the same time, games using the fictional worlds of Star Trek , DC Heroes , the Marvel Universe or The Lord of the Rings expanded the range of possibilities for Table-top gaming. Games such as GURPS and Champions introduced character creation via point-buy systems; later, Vampire: The Masquerade and similar games emphasized storytelling, plot and character development over rules and combat. Due to
7826-406: Was refocused as a role-playing game to segregate it from the typical wargame. One of the first original role-playing games was M. A. R. Barker 's Empire of the Petal Throne , first published in 1974, the same year as Dungeons & Dragons . It introduced the fictional world of Tékumel , influenced by Indian , Middle-Eastern , Egyptian and Meso-American mythology . It also introduced
7917-429: Was released: the Open Gaming License (OGL) made most of the game mechanics of 3rd edition D&D permanently open and available for use as what was known as system reference documents, while the d20 Trademark License allowed publishers to use the official "d20" mark of their products to show compatibility with those from Wizards of the Coast. Unlike the OGL, the d20 License was written so that Wizards could cancel it in
8008-405: Was some criticism of the move, a great many d20 System games were released until around 2008. Meanwhile, indie role-playing game communities arose on the internet, studying role-playing and developing several forms of role-playing game theory such as GNS theory . Rules innovations combined with literary techniques to develop games such as Apocalypse World , The Quiet Year , and Dogs in
8099-484: Was the 1981 Origins Award for Best Roleplaying Rules of 1981 for Call of Cthulhu . Other editions of Call of Cthulhu have also won Origins Awards including the Hall of Fame award.

8190-447: Was the first commercially available role-playing game, though at the time its first printing was marketed as a niche wargaming product. Gygax expected to sell about 50,000 copies total to a strictly hobbyist market. After establishing itself in boutique stores, it developed a strong, lasting fan base that distinguished itself from the typical wargame player base. By the time of its first major reprinting in 1977 , Dungeons & Dragons
8281-489: Was the same as RuneQuest 3rd Edition, but with trademarked elements removed, as Chaosium had lost the rights to the name but retained copyright to the rules text. Additional monographs allowing for new mechanics, thereby extending the system to other genres, were released in the following years. Many of these monographs reproduced rules from other Chaosium-published BRP games that had gone out of print. Jason Durall and Sam Johnson gathered up previous works and updated them to
