I believe that the Forza series is one of the best racing game series ever (alongside Gran Turismo). I prefer Forza series though because I think it has a lot more features than Gran Turismo. Forza has a great physics engine that Gran Turismo obviously lacks and an in-depth customization that would make any car buff drool. I'm definitely going to buy Forza Horizon. Not on launch date though. I'd want to get it at a discounted price. Lol.
