I will name the games that made me go "hmm not bad"

Sunset Overdrive - This game looks like it would be right up my alley
Quantum Break - This also looks like a game around my way.


Honorable Mentions:

Killer Instinct looks pretty good but the free to play stuff kind of fucked it up imo( those free to play games are starting to aggravate me now)

KI sold me, although I would have ended up getting it anyway once Halo 5 releases.

Nothing, really... but I never tried Halo and the trailer they showcased was quite awesome. Sadly I need more than that and I proably won't own one

Kinect voice control is high up there. DR3 and Halo couldn't hurt either

Killer Instinct and Kinect 2.0

Nothing would make me happier than to play KI

Currently: Dead Rising 3
What I want: Something like Lost Odyssey 2... I'd love to see more variety with exclusives, and as of now they are delivering on that, let's see if they can continue that trend.

Edit: I lied, Quantum Break is what initially sold me. DR3 was number 2, followed by Ryse, and then Halo.

There wasn't a single game that sold me on the system. It was a combination of me knowing how much fun I've had with my 360 + the exclusives announced for the X1 + all of the features that they've shown thus far for the X1.

Well I decided long ago never to support MS in the console business. bad for gaming in general imo but I don't fault others for not doing the same.
That being said the line up is pretty good atm. Its not just one game but a few of them. KI, Ryse, Dead Rising 3 are ones I would buy if I was getting the console. IMO it has a much better line up than the other 2

I was gonna say something along these lines but since I know what you really wanna hear, I'll give you a list of what I'm most looking forward to.

Titanfall, Project Spark, Halo 5, Kinect/UI integration and features and dat controller. Also a couple of games that I was initially meh about but will be getting day one, Ryse and DR3. I'm sure I'm forgetting some things but this is off the top.

Not sold but answers would be Sunset Overdrive and TitanFall.

Also hopefully more Alan Wake.
