Do not buy this game!
I know it's a bit late but as this is a website dedicated to collecting achievements i thought everyone should know how glitched the achievements on this game are.
There is another thread with multiple examples of this & it seems there are no patterns.
In my case i haven't received No1 seed, Extreme Champion-Legend or Clean Sweep-Legend.
As you can probably tell these are some of the hardest achievements in the game & i'm totally sick at spending so much time on a game that was hardly any improvement on MotoGP06 anyway [a game i got 1000g on].
Needless to say this'll be my last THQ game! You have been warned.
