Most Wanted is definitely the best NFS game so far. Carbon was good until you took the first 2 territories then after that it started to get pretty damn boring. All the NFS games after Carbon are total shit and shouldn't have had the NFS title put on any of them. I played Underground for about one hour before uninstalling it and never touching it again because of the lame undercover cop story they tried to implement and the horribly unbalanced AI. The handling in Undercover was also messed up along with the way the camera followed the car.
