Summary: MotoGP 10/11 is a big improvement to 09/10 but everytime I go fast, i crash and reset. It is better than 09/10. No more of that "Hey, this isn't mototruck!" guy from 09/10. We have somebody good.
Summary: I don't ever do reviews, but seeing this game selling for $20+ I have to warn people away. MotoGP 08 was great, and MotoGP 13 is awesome as well. Any of the SBK games are worthwhile. Having played all of those, I can say with certainty that MotoGP 09/10 and 10/11 are the two most aggravating racing games I've encountered. The physics make no sense. The bike doesn't ever do what you want it to or what you think it should based on your inputs.
Summary: I played Moto GP 08 like crazy. I loved it. I read that this one was good. I found it to be insanely difficult. I couldn't even keep the bike on the track even after practicing a lot! It also had a bunch of stupid additions to the game play. I hated it.
