I can't see how a 1st racing title for a new-console could have been better. Kudos!
Amazing shinny graphics, outstanding and "fashion" soundtrack, and one very important point that I didn't see at most reviews I've read - the level design: once can easily realize that developers/testers worked hard at this (side-note: I must confess that I consider multiplayer part of of a game as a side-quest - a must side-quest, but still it is - and the core of the game must be it's single campaign, as I don't want to play video games, and appreciate it's quality, based on other things I can't control: other human beeings), because when I first played it, I went through the whole career in 'medium' level and I managed to accomplish that just barely, by the time I finish it I was prepared to go for 'hard', and I feel just the same as in 'medium', it was a fight but a fair one, now I'm heading through 'hardcore' and it feels the same (Kudos!). And then you have the 'novice' that is so, so easy, that it's a good level to let your girlfriend have a try, and she'll feel good for beating it :) !
Another outstanding point: the sound, it is sooooo cool to drive at 300km/h and listen to LCD Soundsystem, it "knocked my socks off"!
Love to see a job well done!
p.s.: X360 haters - open your mind, set yourself free from that silly addiction (Sony, or anything else), and have tons of fun!
