Honestly I'm about there too, I don't play enough games to particularly care about the used bit(aside from tracking down old ones) and I just don't see any games or useful features i'm interested in.
Well so far MS has said approximately fuck all about the games. So far I think these are the only confirmed games but most were confirmed by the devs/publishers not MS:
Assassin's Creed 4 - I'm interested as I rather enjoyed ACII (only one I ever played) and because PIRATES! But it's multiplatform so not enough to convince me to get a One over a PS4.
Battlefield 4 - same as AC4 regarding it being multiplatform. Also I don't know if I still care about BF or not.
Call of Duty: Ghosts - could not give fewer fucks.
Destiny - know very little about this so far (Bungie is being a bi t tight lipped) but I am interest in this one. If it's an exclusive and if it turns out to be interesting it could sway me.
FIFA 14 - mulltiplatform again.
Forza Motorsport 5 - big FM fan so yeah, I'm interested. PS4 will have GT6 but I've started to prefer FM over GT.
Madden 25 - don't care.
NBA Live 14 - don't care.
Quantum Break - no idea what this is or even if it's multi-platform.
Ryse - thnk this is a kinnect game so fuck that noise.
Thief - interested, but again multi-platform.
UFC - don't care.
Watch Dogs - very interest from what little we know about this game so far. But again it's multiplatform.
And I'll eat my own genitals if Halo 5 doesn't show up on the One. And whilst Halo is overated I still quite enjoy it.
So that's only 2 definate exclusives that I give a shit about. It's not really enough so far. Mind you I haven't seen any PS4 exclusives yet that have made me think, "Oh shit, I need that!".
