I don't like the whole you hitting shit doesn't stop your car in the Burnout 4. There was more strategy element when you could only crash your car once.
I just got this game yesterday and I absolutly love it. Its just like burnout 3 with crash mode and all the other modes plus the graphics rock any other portable game out there. My only gripe is the soundtrack... I was hoping for some more heavy shit and bigger names, but that is a minor thing since I dont really pay attention to the music anyways.
