A strange little side quest
Even a quick game like Piggy Roll sits on top of decades — and sometimes centuries — of ideas. Street Fighter II, released in 1991, turned head-to-head arcade fighting into a worldwide phenomenon and helped define the modern fighting-game genre. It also connects to a different milestone: Computer Space reached arcades in 1971 and became one of the earliest commercial electronic arcade games, even though its controls proved demanding for many players. Grombi files that under: small game, surprisingly large backstory.
