Those are all future games, but just to entertain you:
Sunset Overdrive. Yes. However, I'm waiting for more impressions given how bad their last few games were.
Forza Horizon, No.
Fable Legends, No.
Halo, No.
Quantum Break, No. Need more details, Alan wake was a chore.
Gears, Yes.
I leaned against an early XB1 purchase due to price + kinect (I play everything at my desk, with headphones on) + not wanting to pay dual sub fee for MP games.
As for games, Dead Rising was and still is the only game on the system that interest me.
I did the same last gen where I picked up a 360 late just so I can play ToV (and later picked up Gears.)
P.S. I got a PS4 only so I can play BF4 (which I shortly gave up on.)
Do you think I bought that system for any of its other mediocre launches titles?
