I just tried the "extended demo" of this game, and I have to say it's amazing! It's much better than the MotoGP games because it crosses a bit of simulation with the arcade style. Easy to play, but hard to master. There are plenty of classes and bike settings to keep you busy with that quest for fast laps.
The biggest problem is that Black Bean (as far as I can tell) doesn't sell their games in the USA. They wonder why people pirate shit... Not sure why they just don't do a steam release of all of their games. I imagine their sales are hurting big time...
