Everything! Horrible gameplay, horrible objectives, horrible graphics, stupid riders, lame bikes and its near impossible to pull of any tricks...
I hated this game. I am normally a huge fan of dirtbike games but this one just didn't have anything to offer. It has no multi-player modes other than "trick set" which is where you just see who can get the highest score. But, its near impossible to pull off any tricks so it doesn't matter. You literally have to press 6 buttons just to do a simple manual. I hate it!
Overall Outcome: If you see this game, run!!!
