Microgame #16 in the Metagaming Microgames series is a two-player SF wargame of conflict on the Moon centering on an alien artifact called "the dingus." The official rules offer four 10-turn scenarios: three between American and Soviet "research teams" competing for control of the dingus, and one between the Americans and the alien race they've inadvertently summoned with the dingus.
Approximate playing time is a guess.
