The online mode is very fun and addictive. The graphics are of amazing quality (720p) and recommended to all PS3 owner.
The race challenges are also good. The roads are smooth and easy to maneuver through. You really have to get to know your map. Once you've mastered the map, the game is yours. I was a little shocked at first that you have to win EVERY race you participate in. There's no 2nd, 3rd, 4th place. Even if you do fail at one race, there's always another race waiting to be started at the next block.
I have to add the graphics on my 720P set are incredible. All in all, this definitely is a game to add to your collection, PS3 owners. I'm looking forward to more updates in this game in the future.
PS - We need more F1 and Grand Prix-like cars. The Walmart car is sexy and we need more cars like that.
