Micropolis is a city simulation game which means you plan where you want certain aspects of the city established and then watch as the city develops according to your plans.

"Micropolis" is the name of the current GPL open source code version of OLPC SimCity. That was the original working title of Will Wright's city simulation game. Since Micropolis is licensed under the GPL, anyone can do anything they want with it that conforms with the GPL, except they can't call it "SimCity" (and a few other limitations to protect EA's trademarks).
