I agree it's a good racing game. Most of the reviewers even say it's a must-drive for fans of the genre. Looking at some gameplay, it looks great, but the physics seem more arcade than sim. The cutscenes in between races are very NFS; anyone familiar with the series will recognize SHIFT as a NFS game in a heartbeat.
Looking at it, I'm more inclined to fire up my PS2 and play some GT, than go out and get this. I don't think this is really what I'm looking for.
Gonna give the demo a try, we'll see.
