A strange little side quest
Even a quick game like Smarty Bubbles sits on top of decades — and sometimes centuries — of ideas. Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. There is another connection worth keeping in the same mental pocket: Atari's Gran Trak 10 from 1974 is recognized as the first arcade racing video game. Not bad for a few facts hiding behind a Play button.
