Game is definitely cool. If you've played the XBOX versions, you should feel right at home. I like how you can choose between the 05 and 06 rosters.
I also like how the collisions arent as plentiful in this game. In MotoGP 3 for xbox, if another rider rode close to you, you were almost guaranteed to crash. Here, that's not the case.
Biggest gripe is the load times. Holy shit, do they feel long. I also kinda miss the videos.
I beat pro mode easily last night, and started champion mode this morning. So far, not that hard, but then again I put in 23+ seasons in GP 3.
