A strange little side quest
Grombi trivia break for Super Snappy Boomguys: Spacewar! appeared on MIT's PDP-1 in 1962 and became one of the earliest influential computer games shared among programmers. The same trail leads to another fact: 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 history is one reason familiar mechanics can still feel new when they are recombined well.
