Better than American Chopper.
First of all, i like the training mode. Very well thought out. If u beat the training modes, u get points to raise ur own characters stats!
Ya, u heard me. U can actually make ur own rider and bike, with a name and number and everything! Good customization.
Another thing i like is the music. I have said so many freaking times that i love games that let u play ur own soundtracks. And this one does. I love that.
The grand prixs are fun to play as well. When ur about to start the race, there is a hot lady in a bikini beside ur bike. OOH LA LA! =)
There are some extras and bikers to unlock. So the more u play, the more stuff u can get. Too bad u can't buy parts for the bike tho.
Overall, Moto GP is a good game. I like all the game modes, and music, and training and customization and everything! So im gonna give Moto GP an 8.5 outta 10.
