A strange little side quest
Even a quick game like Slenderman Must Die: Abandoned Graveyard sits on top of decades — and sometimes centuries — of ideas. Gun Fight reached arcades in 1975 and became the first arcade video game to use a microprocessor. The timeline takes another interesting turn: Spacewar! appeared on MIT's PDP-1 in 1962 and became one of the earliest influential computer games shared among programmers. Not bad for a few facts hiding behind a Play button.
