''Computer Space'' is the first commercially sold ArcadeGame, created by [[{{Atari}} Nolan Bushnell]] and released in November 1971. It's a one or two player version of ''VideoGame/SpaceWar''. ''Space War'' had previously been software running on [[MainframesAndMinicomputers $20,000 general-purpose hardware]]; Bushnell's innovation was to use cheap logic chips to create a machine specifically for playing this one game.

Some versions were one-player against two flying saucers, others were PlayerVersusPlayer. It's a simplified version of ''Space War'', without the planet and gravity. Your ship fires OneBulletAtATime, and you can guide it by turning your ship. In one-player versions, if you [[ScoringPoints score more points]] than the saucers at the end of [[TimedMission 90 seconds]], you get another 90 seconds of gameplay.

Bushnell created ''Computer Space'' at home, and sold the game to Nutting and Associates, a maker of mechanical coin-op games. It was not a success, because drunks in a bar couldn't understand how to play a game designed for college students. Bushnell left Nutting and founded his own company, Syzygy Corp., later {{Atari}}.
