Forza 2 Custom Paint Jobs are Great!
Here's a game I'm not going to be saying too much about, because, to be honest, I'm not a big car racing fan: I bought this game because my friends both went out and got it, and it's been a long time since we've had a single game we've all been able to play (I like racing OK when I can compete against people I know).
One unexpected feature: The custom car painting feature kicks all kinds of butt!!! With a little practice, you can create some awesome paint jobs. Here are links to a Detroit Tigers themed 1969 Nissan Fairlady that I made this morning (decent, but I'm sure I'll get better with practice):

As a creative guy, the car painting feature (as well as the "community features" that allow me to auction my cars and post pictures on the Forza site directly from my 360) make this worth the money even as a single player affair.
