Rented it the other week and didn't want to take it back, might look into buying it.  The wife will probably end up getting it for my b-day though.  The career was awesome, I was steadily working through Tier II and finally had a 2nd place finish that broke my 1st place streak.  My little Nissan 350 was a little hard to control once I hit all 3 tiers of mods to it.  The thing was just too fast to hold the track, I really had to ease into it and couldn't smack the gas coming out of turns, pretty realistic.  The graphics are amazing too just wish they could cut down a little on the load time.
