My parents got me a XB1 as a gift last year; I might not have bought it if it had been up to me. Nearly a year later and I'm sort of shocked by how few worthwhile games have come out on either the XB1 or PS4. The best games right now are either remakes or DLC games like Killer Instinct. Otherwise I get more play out of my Wii U. One thing I'm pleased about with the XB1 is that the d-pad is finally good. After suffering through the worst d-pads of all time on pretty much any 360 pad outside of a few Horis, it's nice that they finally got it right.
Notable disappointments:
Kinect Sports Rivals: Even if you can get the game to function properly for yourself, it ruins everything when you have friends over and the game doesn't do what it's supposed to. Motion games that fuck up ruin the party mood pretty quickly. "Hey, why doesn't my character turn? I am doing the turning motion" "Yeah.. you sure are. And he's not turning. Uhhh... Let's play Mario Kart."
Crimson Dragon: Actually a decent game, but it should be way better. They could have just done a Panzer Dragoon Orta HD update and it would have been better than Crimson Dragon. It sucks when your new game on your new system is inferior in almost every way to your old game from two generations ago. Yeah, I think the graphics in Orta are just as visually stunning despite lower res. No reason for that.
Titanfall: Played the beta extensively and decided not to buy. Online-only garbage.
Destiny: Obviously multi-platform, but this game is a huge disappointment to me. I liked Halo for the campaign with the occasional deathmatch. Making the game online-only ruins it for me. I have to play games that I can pause at any time due to family obligations.
