Forza Horizon 2 was a system seller for me. Bought an XONE and the game last friday. Then again, I kinda had to get the bland Driveclub taste out of my mouth. Worked wonders. FH2 is all sorts of fun, varied events, cool soundtrack, better progression. Looks amazing, too.
Bought Killer Instict and D4 as well, and preordered. Sunset Overdrive.
I'd be all over Ryse and Dead Rising 3, but I already own them on PC. That crazy-ass Capcom fanservice DLC, tho... I might have to double dip.
