I tried to keep this game aside untill I got a good HD TV, but I couldn't resist!
I'm a huge NFS fan, and this game is wicked. I only give it four stars because, firstly, I'm old school and I like to use the X button to go and the D-Pad to steer, but NFSUndercover only allows you to steer with the analogue sticks. Secondly, I played for maybe an hour when I first tried it and found that I had already gotten a good bit of the way through the game.
Car selection is great, storyline has just enough to keep you interested and the new 'Jobs' feature is alot of fun (stealing vehicles, making deliveries, bashing the bad guys cars off the road)
