So everybody is posting his progress. My progress can be followed at my own blog: http://www.necrosoft.nl.

My progress so far is that I'm busy with my track-spline. I have the calculations in place, but need to fit a 3D model over it. This shouldn't be too hard, so I hope I can finish that this evening or tomorrow.

Next step is to to pass it to Newton Game Dynamics and have a car drive over it. As I already have physics in place this should be a piece of cake.

Next I have to make all the game logic, menu's, AI, decent car physics (all what I have now is a car that drives crappy) + all content.
About content: we planed to make everything in-house...

Thats all for now.
