OpenCity is a free open source 3D city-building game. In the game, the player builds a city by marking land as commercial, industrial or residential zones. Those zones depend on each other to grow. The player is also required to supply the city with power and connect the different zones by building roads.

This is a full 3D city simulator game project. It is written in standard C++ with OpenGL and SDL from scratch. It is not intended to be a clone of any famous city simulator from Max*s. So, if you are looking to download a free SimCity 4 like, please don’t download this. He works on it in his spare time, and he really means it “my spare time” !

This is also an OpenGL/SDL/C++ game programming tutorial. In the resources section, you can find the micro simulators’ algorithm, design document, UML diagram and information about other issues. The UML diagram is edited with Umbrello, the free UML diagram editor for KDE.
