I tried Jello Car, and it's fun except for the fact that it doesn't quite play as well as it should. My system sucks. Either that, or XNA is interpreted, and not compiled like C/C++/Lite-C (I don't know, I've never used it).

I only get maybe 15-20 FPS, and there's no "time_step", as it were, to compensate for the lack of frames.

Code:
void main()
{
    cout << "I am MrCode,";
    cout << "hear me roar!";
    system("PAUSE");
}
