180-573: Sonic the Hedgehog CD , simply known as Sonic CD , is a 1993 platform game developed and published by Sega for the Sega CD . As Sonic the Hedgehog , the player attempts to protect an extraterrestrial body, Little Planet, from Doctor Robotnik . Like other Sonic games, Sonic runs through themed levels while collecting rings and defeating robots. Sonic CD introduces time travel as

360-561: A Pew research poll found that 51% in the United States thought that UFOs reported by people in the military were likely to be evidence of intelligent life from beyond the Earth. In August 2021, Gallup , with a question not specific to military reports, only found that 41% of adults believed some UFOs involve alien spacecraft from other planets. This Gallup poll showed 44% of men and 38% of women believed this. This average of 41% in 2021

540-416: A Sonic game that would demonstrate its more advanced features. Naoto Ohshima , the designer of Sonic, was Sonic CD ' s director; the remainder of the team comprised Sega staff who had developed The Revenge of Shinobi , Golden Axe II , and Streets of Rage . The team built Sonic CD using the original Sonic the Hedgehog code as a base. Sonic CD was conceived as an enhanced port of Sonic

720-537: A game mechanic . By traveling through time, players can access different versions of stages, featuring alternative layouts, music, and graphics. Sonic CD began as a port of the Sega Genesis game Sonic the Hedgehog (1991), but developed into a separate project. Led by Sonic 's co-creator Naoto Ohshima , the developers sought to show off the technical capabilities of the Sega CD. Sonic CD features

900-424: A game over . Sonic CD is differentiated from other Sonic games through its time travel game mechanic , which allows players to access different versions of rounds set in the past, present, and future. The music changes within the different time zones, as remixes of the present music. Sonic starts the first two zones in the present. The third zone is always set in the future, its timeline dependent upon whether

1080-665: A proof-of-concept video of a remastered version of the game, using his Retro Engine , running on iOS . Sega released this version in December 2011 for Android , iOS , PlayStation 3 , and Xbox 360 , and later in January 2012 for Windows via Steam with assistance from BlitWorks in the PC and console ports. The remaster features enhancements such as widescreen graphics, fine-tuned collision detection to make time traveling more consistent, refined visuals and frame rate for Special Stages,

1260-608: A true 3D platformer is a French computer game called Alpha Waves , created by Christophe de Dinechin and published by Infogrames in 1990 for the Atari ST , Amiga , and IBM PC compatibles . Bug! , released in 1995 for the Saturn , has a more conservative approach. It allows players to move in all directions, but it does not allow movement along more than one axis at once; the player can move orthogonally but not diagonally. Its characters were pre-rendered sprites, much like

1440-517: A 1969 USAF document, known as the Bolender memo, along with later government documents, revealed that non-public U.S. government UFO investigations continued after 1970. The Bolender memo first stated that "reports of unidentified flying objects that could affect national security ... are not part of the Blue Book system," indicating that more serious UFO incidents already were handled outside

1620-452: A 1980 arcade release by Universal , is sometimes credited as the first platformer. Another precursor to the genre from 1980 was Nichibutsu 's Crazy Climber , in which the player character scales vertically scrolling skyscrapers. The unreleased 1979 Intellivision game Hard Hat has a similar concept. Donkey Kong , an arcade video game created by Nintendo and released in July 1981,

1800-428: A 1996 poll by Newsweek , 20% of Americans believed that UFOs were more likely to be proof of alien life than to have a natural scientific explanation. In December 2017, a new round of media attention started when The New York Times broke the story of the secret Advanced Aviation Threat Identification Program that was funded from 2007 to 2012 with $ 22 million spent on the program. Following this story, along with

1980-401: A 2D plane are called 2.5D , as they are a blend of 2D and 3D. The first platformers to simulate a 3D perspective and moving camera emerged in the early-mid-1980s. An early example of this was Konami 's Antarctic Adventure , where the player controls a penguin in a forward-scrolling third-person perspective while having to jump over pits and obstacles. Originally released in 1983 for

2160-500: A 3D Sonic game, Sonic Adventure , for its Dreamcast console. It used a hub structure like Super Mario 64 , but its levels were more linear, fast-paced, and action-oriented. UFO An unidentified flying object ( UFO ), or unidentified anomalous phenomenon ( UAP ), is any perceived airborne, submerged or transmedium phenomenon that cannot be immediately identified or explained. Upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while

2340-505: A UFO and reported recovered memories of their experience that became ever more elaborate as the years went by. In 1966, 5% of Americans reported to Gallup that "they had at some time seen something they thought was a 'flying saucer'", 96% said "they had heard or read about flying saucers", and 46% of these "thought they were 'something real' rather than just people's imagination". Responding to UFO enthusiasm, there have always been consistent yet less popular efforts made at debunking many of

2520-462: A balance between open-ended and guided exploration. Another platform-adventure released that year, Pony Canyon 's Super Pitfall , was critically panned for its vagueness and weak game design. That same year Jaleco released Esper Boukentai , a sequel to Psychic 5 that scrolled in all directions and allowed the player character to make huge multistory jumps to navigate the vertically oriented levels. Telenet Japan also released its own take on

2700-413: A ball, and collects rings as a form of health. Sonic can also perform a "spin dash" and a "super peel-out", both of which increase his speed. The game has seven levels ; each is split into three zones, the third of which ends in a boss fight against Robotnik. Players start with three lives , which are lost when they suffer any type of damage without rings in their possession; losing all lives results in

2880-517: A bitmap and animation editor. The team mostly used Macintosh IIcis . Graphics data was stored on 3.5-inch floppy disks, which were handed to the programmer to work into the game. Though Naka was not directly involved with Sonic CD , he exchanged design ideas with Ohshima. Ohshima cited the film Back to the Future (1985) as an influence on the time travel. The developers designed four variants of each stage (one for each time period). Ohshima hoped for

3060-481: A bouncing car that jumps on various platforms such as buildings, clouds, and hills. Jump Bug offered a glimpse of what was to come, with uneven, suspended platforms, levels that scroll horizontally (and in one section, vertically), and differently themed sections, such as a city, the interior of a large pyramid, and underwater. Irem's 1982 arcade game Moon Patrol combines jumping over obstacles and shooting attackers. A month later, Taito released Jungle King ,

3240-525: A brief burst of episodic platformers where the first was freely distributed and parts 2 and 3 were available for purchase. The abundance of platformers for 16-bit consoles continued late into the generation, with successful games such as Vectorman (1995), Donkey Kong Country 2: Diddy's Kong Quest (1995), and Super Mario World 2: Yoshi's Island (1995), but the release of new hardware caused players' attention to move away from 2D genres. The Saturn , PlayStation , and Nintendo 64 nevertheless featured

3420-473: A daily occurrence with one particularly famous example being the Roswell incident in 1947 where remnants of a downed observation balloon were recovered by a farmer and confiscated by military personnel. UFO enthusiasts in the early 1950s started to organize local "saucer clubs" modeled after science fiction fan clubs of the 1930s and 1940s, with some growing to national and international prominence within

3600-562: A decade. In 1950, three influential books were published— Donald Keyhoe 's The Flying Saucers Are Real , Frank Scully 's Behind the Flying Saucers , and Gerald Heard 's The Riddle of the Flying Saucers . Each guilelessly proposed that the extraterrestrial UFO hypothesis was the correct explanation and that the visits were in response to detonations of atomic weapons . These books also introduced Americans to, as Eghanian puts it, "the crusading whistleblower dedicated to breaking

3780-407: A familiar object." The regulation also said UFOBs were to be investigated as a "possible threat to the security of the United States" and "to determine technical aspects involved." The regulation went on to say that "it is permissible to inform news media representatives on UFOB's when the object is positively identified as a familiar object" but added: "For those objects which are not explainable, only

3960-762: A few weeks later in October. After being delayed for the new soundtrack, it was released in North America in November 23, 1993 alongside Sonic Chaos and Sonic Spinball as part of Sega of America's "Sonic Three on One Day" release strategy. Sonic CD was the flagship game for Sega CD and its only Sonic game. An enhanced version of the original Sonic the Hedgehog and a Sonic -themed port of Popful Mail were canceled. Two versions of Sonic CD were released for Windows : one in 1995 for Pentium processors , and another in 1996 for DirectX . The Pentium version

4140-450: A forward-scrolling effect similar to Sega's 1985 third-person rail shooter Space Harrier . 3-D WorldRunner was an early forward-scrolling pseudo-3D third-person platform-action game where players were free to move in any forward-scrolling direction and could leap over obstacles and chasms. It was notable for being one of the first stereoscopic 3-D games . Square released its sequel, JJ , later that year. The earliest example of

4320-419: A good future in each zone, players must travel to the past and destroy a hidden transporter where enemy robots spawn. Achieving a good future in every zone unlocks the game's best ending. By finishing a level with more than 50 rings, Sonic can access a special stage, in which he must destroy six UFOs in a pseudo-3D environment within a time limit. Time is reduced swiftly if the player runs through water, though

4500-609: A high quality of animation. The 1988 shareware game The Adventures of Captain Comic was one of the first attempts at a Nintendo-style platformer for IBM PC compatibles . It inspired Commander Keen , released by id Software in 1990, which became the first MS-DOS platformer with smooth scrolling graphics. Keen's success resulted in numerous console-styled platformers for MS-DOS compatible operating systems, including Duke Nukem , Duke Nukem II , Cosmo's Cosmic Adventure , and Dark Ages all by Apogee Software . These fueled

4680-533: A more bold, experimental sound that matched his vision for Sonic CD. This led to the composers crafting the game's music around club and house music, inspired by the scene's increasing popularity in Japan, and how Sonic's image was being used in the UK at the time. The vocal theme, "Cosmic Eternity", was the first track approved by Ohshima, becoming the foundation for the rest of the score. Even after approving their concept for

4860-631: A number of successful 2D platformers. The 2D Rayman was a big success on 32-bit consoles. Mega Man 8 and Mega Man X4 helped revitalize interest in Capcom 's Mega Man character . Castlevania: Symphony of the Night revitalized its series and established a new foundation for later Castlevania games. Oddworld and Heart of Darkness kept the subgenre born from Prince of Persia alive. The difficulties of adapting platformer gameplay to three dimensions led some developers to compromise by pairing

5040-427: A phenomenon could, in fact, occur". The research was "being conducted with the thought that the flying objects might be a celestial phenomenon," or that "they might be a foreign body mechanically devised and controlled." Three weeks later in a preliminary defense estimate, the air force investigation decided that, "This 'flying saucer' situation is not all imaginary or seeing too much in some natural phenomenon. Something

5220-622: A professor of philosophy and religion at the University of North Carolina, says that what is seen on a screen, "if it conforms to certain criteria, is interpreted as real, even if it is not real and even if one knows it is not real" and that "screen images embed themselves in one's brain and memories" in ways that "can determine how one views one's past and even determine one's future behaviors". The most notable cases of UFO sightings in France include: UFOs have been subject to investigations over

5400-441: A quarter and a third of all console games. By 2006, the genre had experienced a decline in sales, representing a 2% market share as compared to 15% in 1998. In spite of this, platformers are still being commercially released every year, including some which have sold millions of copies. A platformer requires the player to maneuver their character across platforms to reach a goal while confronting enemies and avoiding obstacles along

5580-467: A series of sensationalized Pentagon UFO videos leaked by members of the program who became convinced that UFOs were genuine mysteries worth investigating, there was an increase in mainstream attention to UFO stories. In July 2021, Harvard astronomer Avi Loeb announced the creation of his Galileo Project which intended to use high-tech astronomical equipment to seek evidence of extraterrestrial artifacts in space and possibly within Earth's atmosphere. This

5760-470: A shift in design. Later 3D platformers like Banjo-Kazooie , Spyro the Dragon , and Donkey Kong 64 borrowed its format, and the "collect-a-thon" genre began to form. In order to make this free-roaming model work, developers had to program dynamic, intelligent cameras. A free camera made it harder for players to judge the height and distance of platforms, making jumping puzzles more difficult. Some of

5940-406: A side-scrolling action game some platform elements: jumping between vines, jumping or running beneath bouncing boulders. It was quickly re-released as Jungle Hunt because of similarities to Tarzan . The 1982 Apple II game Track Attack includes a scrolling platform level where the character runs and leaps along the top of a moving train. The character is little more than a stick figure , but

6120-549: A small number remain unexplained. While unusual sightings have been reported in the sky throughout history, UFOs became culturally prominent after World War II , escalating during the Space Age . Studies and investigations into UFO reports conducted by governments (such as Project Blue Book in the United States and Project Condign in the United Kingdom ), as well as by organisations and individuals have occurred over

6300-492: A special UFO that appears when time is running out grants extra time if destroyed. If the player destroys all the UFOs before the time runs out, they earn a Time Stone. Collecting all seven Time Stones automatically creates a good future in every zone, unlocking the best ending. The game also features a time attack mode, where players can replay completed levels for the fastest time possible; a "D.A. Garden", where players can listen to

6480-725: A teenager with a rebellious personality to appeal to gamers who saw the previous generation of consoles as being for kids. The character's speed showed off the hardware capabilities of the Genesis, which had a CPU clock speed approximately double that of the Super NES. Sonic 's perceived rebellious attitude became a model for game mascots. Other companies attempted to duplicate Sega's success with their own brightly colored anthropomorphisms with attitude. These often were characterized by impatience, sarcasm, and frequent quips. A second generation of platformers for computers appeared alongside

6660-442: A threat to national security. Officials were concerned about the "risk of false alerts", of "falsely identifying the real as phantom", and of mass hysteria caused by sightings. In 1947, Brigadier General George F. Schulgen of Army Air Corps Intelligence, warned "the first reported sightings might have been by individuals of Communist sympathies with the view to causing hysteria and fear of a secret Russian weapon." In November 2011,

6840-476: A trail, occasional formation flying, and "evasive" behavior "when sighted or contacted by friendly aircraft and radar", suggesting a controlled craft. It was therefore recommended in late September 1947 that an official Air Force investigation be set up. It was also recommended that other government agencies should assist in the investigation. Project Sign's final report, published in early 1949, stated that while some UFOs appeared to represent actual aircraft, there

7020-529: Is Halley's Comet : first recorded by Chinese astronomers in 240 BC and possibly as early as 467 BC as a strange and unknown "guest light" in the sky. As a bright comet that visits the inner solar system every 76 years, it was often identified as a unique isolated event in ancient historical documents whose authors were unaware that it was a repeating phenomenon. Such accounts in history often were treated as supernatural portents, angels , or other religious omens . While UFO enthusiasts have sometimes commented on

7200-432: Is LESS to these stories than meets the eye". People have always observed the sky and have sometimes seen what, to some, appeared to be unusual sights including phenomena as varied as comets , bright meteors , one or more of the five planets that can be readily seen with the naked eye , planetary conjunctions , and atmospheric optical phenomena such as parhelia and lenticular clouds . One particularly famous example

7380-488: Is central to the genre, though there are exceptions such as Nintendo 's Popeye and Data East 's BurgerTime , both from 1982. In some games, such as Donkey Kong , the trajectory of a jump is fixed, while in others it can be altered mid-air. Falling may cause damage or death. Many platformers contain environmental obstacles which kill the player's character upon contact, such as lava pits or bottomless chasms. The player may be able to collect items and power-ups and give

It reported that "the phenomenon is something real and not visionary or fictitious," and there were disc-shaped objects, metallic in appearance, as big as man-made aircraft. They were characterized by "extreme rates of climb [and] maneuverability", general lack of noise, absence of

8280-465: Is the endless runner , where the main character is always moving forward and the player must dodge or jump to avoid falling or hitting obstacles. Various names were used in the years following the release of the first established game in the genre, Donkey Kong (1981). Shigeru Miyamoto originally called it a "running/jumping/climbing game" while developing it. Miyamoto commonly used the term "athletic game" to refer to Donkey Kong and later games in

8640-595: The AAAS , James E. McDonald said he believed science had failed to mount adequate studies of the problem and criticized the Condon Report and earlier studies by the USAF as scientifically deficient. He also questioned the basis for Condon's conclusions and argued that the reports of UFOs have been "laughed out of scientific court". J. Allen Hynek, an astronomer who worked as a USAF consultant from 1948, sharply criticized

8820-626: The Atari 2600 , with 256 horizontally connected screens, became one of the best-selling games on the system and was a breakthrough for the genre. Smurf: Rescue in Gargamel's Castle was released on the ColecoVision that same year, adding uneven terrain and scrolling pans between static screens. Manic Miner (1983) and its sequel Jet Set Willy (1984) continued this style of multi-screen levels on home computers . Wanted: Monty Mole won

These agencies include

9540-567: The Kenneth Arnold incident . "Unidentified flying object" (UFO) has been in-use since 1947. The acronym, "UFO" was coined by Captain Edward J. Ruppelt , for the USAF. He wrote, "Obviously the term 'flying saucer' is misleading when applied to objects of every conceivable shape and performance. For this reason the military prefers the more general, if less colorful, name: unidentified flying objects. UFO". The term UFO became widespread during

It was bundled with Nintendo systems in North America, Japan, and Europe, and sold over 40 million copies, according to the 1999 Guinness Book of World Records . Its success as a pack-in led many companies to see platformers as vital to their success, and contributed greatly to popularizing the genre during the third and fourth generations of video game consoles. Sega attempted to emulate this success with their Alex Kidd series, which started in 1986 on

In 1961, the first alien abduction account was sensationalized when Barney and Betty Hill underwent hypnosis after seeing

26280-453: The team used a format that provided uncompressed imagery to the video display processor, which allowed for superior results in contrast to the Cinepak compression used for other Sega CD games. The special stages feature Mode 7 -like background plane manipulation effects. An underground dungeon stage was cut early in development as it did not fit the Sonic gameplay. The original soundtrack

26460-962: The term UFO has generally become synonymous with alien spacecraft . The term "extra-terrestrial vehicle" (ETV) is sometimes used to separate this explanation of UFOs from totally earthbound explanations. Studies show that after careful investigation, the majority of UFOs can be identified as ordinary objects or phenomena. The 1952–1955 study for the USAF used the following categories: "Balloon; Astronomical; Aircraft; Light phenomenon; Birds, Clouds, dust, etc.; Insufficient information; Psychological manifestations; Unknown; and Other". The most commonly found identified sources of UFO reports are: An individual 1979 study by CUFOS researcher Allan Hendry found, as did other investigations, that fewer than one percent of cases he investigated were hoaxes and most sightings were actually honest misidentifications of prosaic phenomena. Hendry attributed most of these to inexperience or misperception. Astronomer Andrew Fraknoi rejected

26640-521: The time period to change instantly with a "sonic boom" effect, but the programmers argued this was impossible and produced a loading sequence instead. Sega did not pressure the team developing Sonic CD as much as the one developing Sonic 2 . Ohshima felt this was because Sonic CD is not a numbered sequel; he considered it a recreation of the original game. The total game data of Sonic CD is 21 megabytes (MB), compared to Sonic 2 ' s 1 MB. The game includes animated cutscenes produced by Studio Junio;

26820-431: The time travel—coupled with large levels rich with secrets and Super Mario Kart -like special stages—added replayability . Sega Pro also noted the expanded environments and the replay value travel added by the time travel, writing that "the more you play Sonic CD the better it gets", but felt the game was too easy. In its debut issue, Sega Magazine said Sonic CD was "potentially a classic". GameSpot singled out

27000-441: The time. Despite this, Yoshi's Story sold over a million copies in the US, and Mischief Makers rode high on the charts in the months following its release. The term 3D platformer usually refers to games with gameplay in three dimensions and polygonal 3D graphics. Games that have 3D gameplay but 2D graphics are usually included under the umbrella of isometric platformers , while those that have 3D graphics but gameplay on

27180-540: The top down perspective, Frogger (1981) as climbing games. In a December 1982 Creative Computing review of the Apple II game Beer Run , the reviewer used a different term: "I'm going to call this a ladder game, as in the 'ladder genre,' which includes Apple Panic and Donkey Kong ." That label was also used by Video Games Player magazine in 1983 when it named the Coleco port of Donkey Kong "Ladder Game of

27360-405: The traits Hoshino looked for in women at the time. Hoshino designed Metal Sonic in response to Ohshima wanting a strong rival for Sonic. Hoshino had a clear image of Metal Sonic in his mind from the moment he was briefed, and his design emerged after only a few sketches. The character graphics were created using Sega's proprietary graphics system for the Genesis, the "Sega Digitizer MK-III", featuring

27540-437: The video game industry internationally. The following year, Donkey Kong received a sequel, Donkey Kong Jr. and later Mario Bros. , a platformer with two-player cooperative play . It laid the groundwork for other two-player cooperative games such as Fairyland Story and Bubble Bobble . Beginning in 1982, transitional games emerged with non-scrolling levels spanning multiple screens. David Crane's Pitfall! for

27720-455: The visual flash of 3D with traditional 2D side scrolling gameplay. These games are often referred to as 2.5D. The first such game was Saturn launch title , Clockwork Knight (1994). The game featured levels and boss characters rendered in 3D, but retained 2D gameplay and used pre-rendered 2D sprites for regular characters, similar to Donkey Kong Country . Its sequel improved upon its design, featuring some 3D effects such as hopping between

27900-428: The way. These games are either presented from the side view, using two-dimensional movement, or in 3D with the camera placed either behind the main character or in isometric perspective . Typical platforming gameplay tends to be very dynamic and challenges a player's reflexes, timing, and dexterity with controls. The most common movement options in the genre are walking, running, jumping, attacking, and climbing. Jumping

28080-554: The years that varied widely in scope and scientific rigor. Governments or independent academics in the United States, Canada, the United Kingdom, Japan, Peru, France, Belgium, Sweden, Brazil, Chile, Uruguay, Mexico, Spain, and the Soviet Union are known to have investigated UFO reports at various times. No official government investigation has ever publicly concluded that UFOs are indisputably real, physical objects, extraterrestrial in origin, or of concern to national defense. Among

28260-410: The years without confirmation of the fantastical claims of small but vocal groups of ufologists who favour unconventional or pseudoscientific hypotheses, often claiming that UFOs are evidence of extraterrestrial intelligence , technologically advanced cryptids , demons , interdimensional contact or future time travelers . After decades of promotion of such ideas by believers and in popular media,

28440-413: Was Floating Runner , developed by a Japanese company called Xing and released for PlayStation in early 1996, before the release of Super Mario 64 . Floating Runner uses D-pad controls and a behind-the-character camera perspective. In 1996, Nintendo released Super Mario 64 , which is a game that set the standard for 3D platformers. It let the player explore 3D environments with greater freedom than

28620-417: Was a major commercial success and positioned Sega as Nintendo 's main rival in the console market. The lead programmer, Yuji Naka , dissatisfied with Sega of Japan's rigid corporate policies, moved with several members of Sonic Team to the United States to develop Sonic the Hedgehog 2 with Sega Technical Institute (STI). Meanwhile, Sega planned to release the Sega CD add-on for its Genesis , and wanted

28800-505: Was a primary way to attack. This was the first true 3D platform-action game with free-roaming environments, but it was never ported to another platform or released outside Japan, so it remains relatively unknown in the West. The following year, Exact released their follow-up to Geograph Seal . An early title for Sony's new PlayStation console, Jumping Flash! , released in April 1995, kept

28980-560: Was called off after the Robertson Panel's negative conclusions in January 1953. Project Sign was dismantled and became Project Grudge at the end of 1948. Angered by the low quality of investigations by Grudge, the Air Force Director of Intelligence reorganized it as Project Blue Book in late 1951, placing Ruppelt in charge. J. Allen Hynek , a trained astronomer who served as a scientific advisor for Project Blue Book,

29160-489: Was composed by Naofumi Hataya and Masafumi Ogata, who had worked together on the 8-bit version of Sonic the Hedgehog 2 . It features two songs, "Sonic — You Can Do Anything" (often referred to as "Toot Toot Sonic Warrior"), composed by Ogata and originally written for Sonic the Hedgehog 2 , and "Cosmic Eternity — Believe in Yourself", composed by Hataya. Both are sung by Keiko Utoku . Hataya and Ogata's initial demo songs were rejected by director Naoto Ohshima, who insisted on

29340-514: Was considered so urgent that OS/I drafted a memorandum from the DCI to the NSC proposing that the NSC establish an investigation of UFOs as a priority project throughout the intelligence and the defense research and development community. It also urged the DCI to establish an external research project of top-level scientists, now known as the Robertson Panel to analyze the problem of UFOs. The OS/I investigation

29520-402: Was eventually released on 23 November 2011, consisting of the complete original soundtrack for the game, with select bonus tracks based on the US score. A remix album, titled Sonic The Hedgehog - REMIX , would be released in Japan in late 1994, consisting of arranged versions of select tracks from the game, also composed by Hataya and Ogata. In the United States, the album Sonic The Hedgehog Boom

29700-432: Was followed closely by the publication of Loeb's book Extraterrestrial , in which he argued that the first interstellar comet ever observed, 'Oumuamua , might be an artificial light sail made by an alien civilization. Two government sponsored programs, NASA's UAP independent study team and the All-domain Anomaly Resolution Office were charged in part by Congressional fiat to investigate UFO claims more fully, adopting

29880-532: Was found in any previous game in the genre. With this in mind, Nintendo put an analog control stick on its Nintendo 64 controller, a feature that had not been seen since the Vectrex but which has since become standard. The analog stick provided the fine precision needed with a free perspective. In most 2D platformers, the player finished a level by following a path to a certain point, but in Super Mario 64 ,

30060-538: Was included in the 2022 compilation Sonic Origins , which removed voice lines for Sonic and Amy. Amy herself and Knuckles also became selectable characters for the game in a later update to Origins. The Sega CD version sold more than 1.5 million copies, making it the system's best-seller. In the United Kingdom, it was the top-selling Mega CD game in December 1993. The game received critical acclaim. The presentation, visuals, and audio were praised. Computer and Video Games wrote that, although Sonic CD did not use

30240-418: Was initially skeptical of UFO reports, but eventually came to the conclusion that many of them could not be satisfactorily explained and was highly critical of what he described as "the cavalier disregard by Project Blue Book of the principles of scientific investigation". Leaving government work, he founded the privately funded CUFOS , to whose work he devoted the rest of his life. Other private groups studying

30420-477: Was not enough data to determine their origin. The Air Force's Project Sign was created at the end of 1947, and was one of the earliest government studies to come to a secret extraterrestrial conclusion. In August 1948, Sign investigators wrote a top-secret intelligence estimate to that effect, but the Air Force Chief of Staff Hoyt Vandenberg ordered it destroyed. The existence of this suppressed report

30600-467: Was not universal in the CIA, however, as fellow NICAP official Donald E. Keyhoe wrote that Vice Admiral Roscoe Hillenkoetter , the first director of the CIA, "wanted public disclosure of UFO evidence". Official U.S. Air Force interest in UFO reports went on hiatus in 1969 after a study by the University of Colorado led by Edward U. Condon and known as the Condon Report concluded "that nothing has come from

30780-477: Was only bundled with new computers and never sold in stores; Sega worked with Intel to make the game work properly. The DirectX version was released under the Sega PC label, and it was released in North America on July 8 and in Japan on August 9. This version is mostly identical to the original release, but loading screens were added and it is only compatible with older versions of Windows. Both Windows versions use

30960-553: Was released in February 1994, consisting of extended versions of most of the game's American soundtrack, as well as arrangements based on Sonic Spinball. An unofficial four-CD tribute album, Temporal Duality: A Sonic CD ReMix Album , was released by OverClocked ReMix in 2013, made up of 45 arrangements based on both the original and North American Sonic CD soundtracks. Sonic CD was released in Japan on September 23, 1993 and in Europe

31140-586: Was released in late 1993. It received critical acclaim and is often called one of the best Sonic platform games. Reviewers praised its size, music, and time travel feature, although some felt it did not fully use the Sega CD's capabilities. It sold over 1.5 million copies, making it the bestselling Sega CD game. Sonic CD was ported to Windows as part of the Sega PC label in 1996, and to the PlayStation 2 and GameCube as part of Sonic Gems Collection in 2005. A remake , developed by Christian Whitehead using

31320-407: Was replaced by Project Grudge up through 1951. In the third U.S. Air Force program, from March 1952 to its termination in December 1969, "the U.S. Air Force cataloged 12,618 sightings of UFOs as part of what is now known as Project Blue Book ". In the late 1950s, public pressure mounted for a full declassification of all UFO records, but the CIA played a role in refusing to allow this. This sense

31500-515: Was reported in 1947, Gallup published a poll asking people in the United States what the "flying saucers" might be. Already, 90% had heard of the new term. However, as reported by historian Greg Eghanian, "a majority either had no idea what they could be or thought that witnesses were mistaken" while "visitors from space were not initially among the options that anyone had in mind, and Gallup didn't even mention if anyone surveyed brought up aliens. Within weeks, reports of flying saucer sightings became

31680-572: Was revealed by several insiders who had read it, such as astronomer and USAF consultant J. Allen Hynek and Capt. Edward J. Ruppelt, the first head of the USAF's Project Blue Book. Another highly classified U.S. study was conducted by the CIA's Office of Scientific Investigation (OS/I) in the latter half of 1952 in response to orders from the National Security Council (NSC). This study concluded UFOs were real physical objects of potential threat to national security. One OS/I memo to

31860-418: Was the first game to allow players to jump over obstacles and gaps. It is widely considered to be the first platformer. It introduced Mario under the name Jumpman. Donkey Kong was ported to many consoles and computers at the time, notably as the system-selling pack-in game for ColecoVision , and also a handheld version from Coleco in 1982. The game helped cement Nintendo's position as an important name in

32040-427: Was thought the mysterious objects were possibly Russian tests of captured German V1 or V2 rockets , but most were identified as natural phenomena as meteors. Many scholars, especially those arguing for the psychosocial UFO hypothesis , have noted that UFO characteristics reported after the first widely publicized modern sighting by Kenneth Arnold in 1947 resembled a host of science fiction tropes from earlier in

32220-433: Was up from 33% in a 2019 Gallup poll with the same question. Gallup further found that college graduates went in 2019 from being the least likely educational group to believe this to being on par in 2021 with adults who have no college education. An October 2022 poll by YouGov only found that 34% of Americans believe that UFOs are likely to involve alien life forms. Historian Greg Eghigian wrote in August 2021 that "over

32400-540: Was used in Steve Bloom's 1982 book Video Invaders and 1983 magazines Electronic Games (US)—which ran a cover feature called "The Player's Guide to Climbing Games"—and TV Gamer (UK). Bloom defined "climbing games" as titles where the player "must climb from the bottom of the screen to the top while avoiding and/or destroying the obstacles and foes you invariably meet along the way." Under this definition, he listed Space Panic (1980), Donkey Kong , and despite
