RR7 (Ridge Racer 7) and NFSC (Need for Speed Carbon) are the only two full racing games available for the PS3.  Of course, Grand Turismo HD is available for download at the Playstation Store, and when the full version is released it will by far be the best racing game EVER.  But for the time being, there is no doubt that NFSC is the better racing game.

I rented both RR7 and NFSC.  I played NFSC for the entire five days I had it, but RR7 on the other hand, I only played for about 5 minutes and quit.

RR7 is very unrealistic, and it's more about drifting around corners than anything.  It's a total arcade type of racer, and there is almost no skills needed to play the game.  In addition, there is no story, unlike the NFS series.  RR7 also does not have any licensed cars, unlike NFSC.  Bottom line, get RR7 if you're looking for a simple racer, where the learning curve is about 2 minutes.  If you're looking for a racing game that requires more skillful driving and realistic driving, get NFSC.
