Talking about racing games. I fell in LOVE with Forza 5 on the xbox one. Its crazy because the graphics are nearly lifelike and the gas and brake triggers vibrate. You dont realize how much of a game changer that can be when you shut all the assists off. That is probably my favorite xbox one game so far besides Halo MCC edition. I'm a huge halo freak, not because of the online but because of the story.
And PBJman, take your time before you move into the next gen, both systems have alot of frusterating issues to work out, but if i can make a suggestion, if you do finally get an xbox one, DEFINITELY get it with the connect, WOWZA what a cool thing!
