I'm loving NFS shift! It's the first good NFS after most wanted.
NFS Carbon was just a copy-paste of most wanted, with the car models changed and the gang system added. You even had the EXACTLY SAME music while you was in a cop chase! The only good thing about NFS:C was the drift mode.
NFS:Pro street.. sucked balls, the driving was shit. NFS:Undercover... I don't think I played it for more than 10 minutes after seeing all the glitches it had, the extremly sucky driving, the extremly poor performance, etc..
I think that NFS:Shift is kinda a come back from the downhill the NFS saga had been going trough, I'm glad that EA dropped the NFS development, since lastly, EA games isn't doing a single working thing for the PC, every release from EA for PC is just another fail. Just look, they are still working on a patch to make The Saboteur work with ATI cards! Just wow.
