A strange little side quest
Even a quick game like Military Wars 3D Multiplayer sits on top of decades — and sometimes centuries — of ideas. Games resembling checkers were being played thousands of years ago; evidence of related games reaches back to around 1600 BC. It also connects to a different milestone: Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. The details change, but the appeal of learning a system and trying again is remarkably persistent.
