SimCity

From Wikipedia:

SimCity is a city-building simulation game, first released in 1989 and designed by Will Wright. SimCity was Maxis' first product, which has since been ported into various personal computers and game consoles, and spawned several sequels including SimCity 2000 in 1993, SimCity 3000 in 1999, SimCity 4 in 2003, SimCity DS, and SimCity Societies in 2007. The original SimCity was later renamed SimCity Classic. Until the release of The Sims in 2000, the SimCity series was the best-selling line of computer games made by Maxis.

SimCity spawned a series of Sim games. Since the release of SimCity, similar simulation games have been released focusing on different aspects of reality such as business simulation in Capitalism.
