so far i only noticed is that when you race same track again its usaully in reverse and a different setting...like one of the rally tracks is in day and then you play it in a reverse race and its dawn..when you race in daytime you finish in daytime. oh yeah the rain tracks are freaking awesome!!!..i\'m almost done,,,i need 4 more races in arcade mode and two more licenses. the liscenses are fun getting cause when you lose you can race or compete against the ghost mode of your previous race to help you get better.,,,,oh yeah has anyone ever heard of GT3 rage???....i have it,,,damn near threw the controller across the room,,i was winning a race and all of a sudden this skyline blast past me,,like he had a turbo button...i was pissed i let out a mighty roar and counted to 10....its just a game ..its just a game...whew!!!
