The open source version will be called Micropolis (the initial name for Sim City), since EA retains the trademark Sim City.
The version shipped on OLPC laptops will still be called Sim City, but will have to be tested by EA quality assurance before each release to be able to use that name.
Sim City was released in 1990 on the ZX Spectrum 48K & 128K by Infrogrames, programmed by Probe Software Ltd - Antony R. On January 10, 2008, the Sim City source code was released under the free software GPL 3 license.
The release of the source code was related to the donation of Sim City software to the One Laptop Per Child laptop, as one of the principles of the OLPC laptop is the use of free and open source software.
Wright soon found he enjoyed creating maps more than playing the actual game, and so the idea for Sim City was created.
In addition, Wright also was inspired by reading "The Seventh Sally", a short story by Stanisław Lem from The Cyberiad, published in the collection The Mind's I, in which an engineer encounters a deposed tyrant, and creates a miniature city with artificial citizens for the tyrant to oppress.
Sim City was originally developed by game designer Will Wright.
The inspiration for Sim City came from a feature of the game Raid on Bungeling Bay that allowed Wright to create his own maps during development.The player (acting as mayor) is given a blank map to begin and must expand the city with the budget provided.As the city matures, the player may get to place government and other special buildings (such as a mayor's house or courthouse), depending on how large the city is.The player must supply the citizens services, which include health, education, safety, parks and leisure.These come in the form of different buildings, where each building covers a circular "range" of service.Inadequate funding of these services can lead to strikes.
