Heh, I played the demo of Shift and all I could think was "holy shit, they just repackaged GRID with a lamer interface!".
And I KNOW the reason is "it's easier to do", but why is it that DLC for racing games always means "more cars"? AFAIK, only Burnout Paradise actually added more drivable area as DLC (altho not on the PC, those bastards).
