Played this demo yesterday with the Micro$oft wheel I bought last year. Just blown away! I 'm really not into simulations that much, and Forza 2 really didn't do too much for me, but this game felt great. It also FINALLY made me feel like I got my moneys worth for the wheel.
The in-cockpit camera angle has great detail, all the way to the different dash layouts as you change cars, to the cars can be seen moving in your rear view mirror. When you turn on the collision damaged in the game with the force feedback steering wheel you can feel the car start to pull in the direction of any sustained damage to the car. Trivial I know to some but I found it quite impressive. I believe I'll have to buy this one...8^)
