Welcome to Theme Park Builder 3D - an ambitious open source project to create a free amusement park construction game. You can build a huge park and then take a first person view and "ride the rides". Key features include user created content and expandability. This will be a multiplatform (Windows, Linux, Mac OS X) game. The coding project is hosted on SourceForge and will be released under the GPL
