I've had my Xbone for almost a month now.
Games in my collection
Dead Rising 3 - A lot of early nitpicking on it not looking like a next gen game, but I find it to look well enough. Haven't been able to get too deep into it because of...
..Titanfall - I dig it, plain and simple. This was the main reason I wanted a Bone, and it's a blast to play. Even my youngest daughter is hooked, as we'll take turns passing the controller back and forth like we used to do with Blops 2.
Forza 5 - Pack in game, and another title I recalled hearing wasn't visually impressive. Uh, I finally booted it up a few days ago, and it's damn fine looking! Only messed with it for a bit, but being a big fan of Forza 3 I know it's going to be great.
Killer Instinct- Well, the "free" demo with the rotating character selection, but I plan on buying it. Not a huge fighting game fan, but I do enjoy the spectacle.
Ryse - Beaten and returned so I no longer have this, but I LOVED my time with it. Visually the best looking new gen game I've seen period. Can't recommend it enough!
The two free GwG titles. They both seem kinda meh so far. Thankfully we're getting Guacamelee this month!
Preordered
Sunset Overdrive
Halo Collection
Forza Horizon 2
Near future...
I don't see myself keeping the preorders for Halo Collection and Forza Horizon 2. I'll most likely be switching them to GTA V, and CoD AW. I'm sure the PS4 version of CoD AW will be 1080p, but I really don't care as I like the idea of getting my dlc a month in advance, when I'm really into the game.
Overall I feel the PS4 is the better machine in terms of hardware, and PS Plus service. In terms of games I feel the Xbone has it all over the PS4 right now. It's a no contest, right now.
