Slot car racing sandbox
This is a decent game.... or should I say, sandbox. There are 2 ways to host races- one where you take control of the last car, or a full-cpu race, where all the cars are driven full-throttle. Track building is both fun and challenging- there are 3 axis in the game: X and Y allow you to adjust the length of the tracks and the width of turns, and the Z axis allows you to raise the track, but only at a junction. This allows you to build bridges. Be careful of how big your tracks get, or the game will freeze.
