Nolan Bushnell developed this commercial version of the classic video game SpaceWar! nine years after it had been developed on the PDP-1 in 1962. Computer Space became the first commercial arcade video game. It pitted solo players against alien spaceships, or two competing players against each other. Although Computer Space sold poorly, it got high marks for its futuristic cabinet. Bushnell later founded Atari and Chuck E Cheese’s Pizza-Time Theaters.
