A strange little side quest
If Biozombie of Evil 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. A second detail makes the picture even better: Space Invaders arrived in 1978 and helped turn electronic games from an arcade curiosity into mainstream entertainment. It is a good reminder that simple game mechanics can carry a surprising amount of history.
