Actually the worst part is online mode. Everyone has a damn infinite NO2 hack, and EA does nothing about it.
Actually, the games are completely different styles. Tokyo Xtreme Racer is all about unorganized (event wise) street racing on the highways, while NFS:U is about organized race events on city streets, and more bling than you can shake a stick at. They are both very good games for what they are, but they aren't real competition for each other. I've played some version of Tokyo Xtreme Racer and like it, but it wasn't for PC and NFS:U is, so...
