SimCity is an open-ended city-building computer and console video game series and the brainchild of developer Will Wright. It is published by Maxis (now a division of Electronic Arts). The game was first published in 1989 as SimCity, and it has spawned several different editions sold worldwide. The ongoing success of SimCity has also sparked the release of many other spin-off "Sim" titles, including 2000's The Sims, the best-selling computer game in history.
In SimCity, the player is given the task of founding a city, while maintaining the happiness of the citizens and keeping a stable budget. In SimCity 2000, SimCity 3000 and SimCity 4, the player is allowed to alter the terrain of the city before building on it.
The player must lay down zones, each having a specific kind of building that will be built there. The residential zones, in green, provide housing for Sims; the commercial zones, in blue, provide shops and offices; and the industrial zones, in yellow, provide factories, laboratories and farms. There are three different densities (two for SimCity 2000) in the game: high density for large buildings, mid-density for mid-sized buildings, and low density for small buildings.
