Better than Gran Tursimo any day
This game is fantastic in every way. Graphically it could use a little work (which it looks like FORZA 3 has taken care of) but as far as all the aspects of racing go (and im not talking retarded Nascar racing here) this game nailed it.
Damage to engine for over reving, tire traction based on tire temp, drafting, proper AI, proper damage... Forza nails it on the head.
Why no 10? Because I dont want to have to race American Muslce cars or 1960 European classics, but if you want useful achievements, you'll have to do those things.
If you want simulation, this is where it's at. Not Gran Tursimo. Speaking of which is that game ever going to come out. GT4 full or GT5 with damage and online play? Forza's online qualifying actually makes it feel like I racing FOR something.
