I kinda got tired of NFS too. I liked most wanted because the cops were back, it was a major fault to leave them out of the previous versions. And I think one of my all time favourite NFS' is road challenge, it was a bit more realistic, not tuning stuff (you could, but you didn't have to). I liked porsche too, some times I just feel like playing it again.
I'll probably end up having the new one too, but I'm preparing for another dissapointment, no matter what the car list is.
