T1 Car Racing Simulation is an open source (GPL) 3D car racing game meant to be executable under both Linux and Windows using the Cygwin emulation layer. If you make it run under some other operating systems, I'd be glad to hear about it. My primary development platform is Linux, but I promise to also test under Windows - at least at release times.

T1 Car Racing Simulation is primarily meant to be fun to play, instead of a full-featured exercise in physics. Expect a solid physics model with a lot of action and some cool graphics. ;-)
