Computer Space is touted as the first ever, coin-operated video arcade machine to be commercially sold. Created by Ted Dabny and Nolan Bushnell — original Atari founders, its gameplay consisted of maneuvering a rocket ship to avoid enemy fire from flying saucers (while firing off missiles to destroy them), using a thruster and rotational buttons — this type of game would later be known as a multi-directional shooter. If you’re score was higher than the computers after each 90-second session, you were rewarded with another round of play. Video after the break. Click here for more pictures.
