A strange little side quest
If Gun Pro Simulator sends you down a curiosity rabbit hole, start here. M.U.L.E. arrived in 1983 with multiplayer competition built around gathering resources and keeping a colony alive, an early example of resource-driven strategy play. There is another connection worth keeping in the same mental pocket: Gun Fight reached arcades in 1975 and became the first arcade video game to use a microprocessor. Not bad for a few facts hiding behind a Play button.
