Stars! is a complex turn-based computer game based around the management of planets and fleets of spaceships following the 4X game model (eXplore, eXpand, eXploit & eXterminate). The game has been around since 1995, and still has a strong following.*From Earthpig04This game was "multiplayer" in the sense that players would have to email data packets to each other that the "host" would process and send back the results to his fellow player/ opponent. Old School game (Windows 3.1 Old School). Definitely worth checking out!
