What are the differences between the two games? I'm playing Forza XBox and I don't see how they could improve on it much. Even the graphics are just about top of the line. Is there really a large graphical improvement to the XBox 360?

Ya bud, you have no idea.

I'll put it this way, I never really cared for Forza 1, Forza 2 I played for 4 weeks straight after buying it.
