Wow, this is an absoloutely brilliant game. The graphics are quite frankly amazing. (By the way, if it's in capital letters it's extra good :d) the multiplayer is fabulous, you can tour round cities in sightseeing mode for one thing. The single player unlocks rock, for instance, if you get a million kudos, you can buy the million kudos gamer picture. Also, there is some bonus dlc, which is great value for money, i mean come on, you get the scuderia! Anyway all in all, a great game, in the official xbox magazine, they gave it 10/10 and the description was: The best racing game ever! (Remember the capital rule there :d)
Anyway, 10/10 from me too, buy cheaply from play.com, add a wheel and have fun.
