A strange little side quest
A quick detour while Hospital Aggression waits for your next move: Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. And then there is this: Pac-Man went on sale in 1980, and its creator Toru Iwatani famously linked the character's shape to a pizza with a slice missing. That long chain of experiments is part of why action games still feels fresh when a game finds the right twist.
