SimCity players build and control simulated cities while reacting to natural and man-made disasters. Designer Will Wright got the idea after realizing that it was more fun to design the simulated worlds for the game Raid on Bungeling Bay than to actually play the game. Wright was also inspired by computer pioneer Jay Forrester’s computer models of cities in his study of system dynamics. SimCity’s success led to dozens of sequels, including The Sims series of life-simulation games.
