Micropolis

Micropolis is an open source version of Sim City, not using the original title's name for copyright reasons. Like the core game, the goal is to develop and maintain a successful city by setting zoning, building roads, organizing power distribution and controlling taxation. In the standard mode, there is no set goal, only to develop your city to meet your own desires without running out of funding. There are also a series of eight scenario cities, each with their own problem to solve within a specific deadline.

The open source version is based on the Unix release of Sim City, and was initially intended for the One Laptop per Child (OLPC) project. Since the source release, it has been included in several Linux distributions and ported to Java, the Web, and other platforms.
