Well, the primitive model (without conversion for the game) is a X-file (Direct-x original file).
Well, there are easier ways to program, for example blender is capable of making complex games in a very easy way, I can make racing games in that (although with no AI nor time nor laps because I haven't learned that yet). But the problem with blender is that the executable file needs loads of dll's in order to work which makes a small game "weigh" a lot on your hard drive...
I've put the X file and the texture in the attachments.
