Not technically the first video game ever made (that honour goes to Tennis For Two, played on a computer nobody had with controls that make GTA 4's driving look smooth), but the first you'd actually wanna play, this two-player shoot 'em up from 1962 was produced by geniuses at MIT with a lot of spare time on their hands. This was where video games started.
19. Pong Brings Them To The Masses
Still, it took a while until computer games were something played by people other than brainboxes at prestigious universities with the technical know-how to make them work. Then, in 1972, Atari brought Pong - their none-more-rudimentary tennis simulator which probably owed more of a debt to Tennis For Two, now that we think about it - to arcades, and the world would never be the same. And just think how crazy people went for Space Invaders when two paddles batting a pixel at each other was considered cutting edge.
