Hmm, not really. The developer behind NFS shift has most of the people responsible for the excellent FIA GTR games involved. It was marketed as a sim type game and while I understand that it's not meant to be as realistic as GTR, it's meant to go a lot of the way.
The shift control scheme and physics are wooden at best, there's very little feel to the cars and while I agree the aural effects are nothing short of awesome the rest of the game sucks a big one. The low level cars are drivable and fun enough, but as you move up the levels to the race cars and the fun stuff like the Zonda R and SpecV, the controls are too sensitive, even with adjustment in the menu, then the cars bounce unrealistically causing more unplayability and crashing.
Nope definitely not my bag. I'm extremely satisfied with my swap for Dirt2 and I'm looking forward to Forza and even more so GT5 later in the year.
