A strange little side quest
Even a quick game like Zombies Shooter sits on top of decades — and sometimes centuries — of ideas. Space Invaders arrived in 1978 and helped turn electronic games from an arcade curiosity into mainstream entertainment. The timeline takes another interesting turn: In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. Not bad for a few facts hiding behind a Play button.
