Ouch...I cannot give a fair review
But as it is I had it in my 360 for about 1 hour...and while the graphics were nice that is all I can say good about the game.
The controls and physics were nothing like what I have ever seen before...the lack of car varieties in the early game dissapointing. The sound seemed to be a handful of generic tracks that left a lot to be desired.
If you aren't sure about the RR series...RENT IT FIRST!!!!!!!! You might be glad you saved $50
