That's actually a good idea.
So is Forza Horizon a simulator in the vein of Gran Turismo and the older Forza games? Or is it more arcadey like Burnout, Midnight Club, or Need for Speed?
I wonder if Forza will now branch out in two directions, with the main series remaining a racing sim with individual racetracks, and Horizon being it's own open-world spinoff series?
I'd love to see more open-world racers (Gran Turismo!), but only a few pulled it off well: Midnight Club, Burnout Paradise, and (supposedly) now Forza Horizon.
