Need for Speed : Shift war eigentlich als NFS Pro Street 2 geplant!

"Yeah. It (Shift) actually started out as ProStreet 2.

You'll see the obvious references, like we've got the Tokyo track in there, albeit a bit more mature; there's no balloons or anything like that. The thing with ProStreet was that they couldn't go straight from street racing to a track racer - that would have annoyed a few people. So it was really the first stage of the transition, mixing courses with the street stuff, and this is where they (EA) always wanted it to go.

We've had a few battles, you know, 'put cops in, put nitrous on everything', but we just said 'come on, let's do this properly, shall we?' And we did. Shift is the game we always wanted to make, just under a different name to how it started."
