I would say Bloodborne now that they have announced procedurally generated dungeons.

bloodborne, hands down!

Uncharted 4.

I can't choose anything but Zelda U, even though it would pain me deeply. So many other good titles for Wii U alone I'd miss, Star Fox and Xenoblade D:

And if I happen to get another system next year that just makes it all that more difficult and soul crushing.
But Zelda is the one game I will always pick over everything else. No other games bring me as much joy.

Wild if come in 2015, uncharted 4 if not.

Zelda U! It looks promising from what I've seen so far! Hopefully it won't disappoint!

Metal Gear Solid V The Phantom Pain.

I can't pick just one game, there are too many, whether it's PS4 exclusives, 3rd party, or Wii U exclusives.
I could go without Halo 5 or Quantum Break, I can't go without Uncharted 4, Ratchet & Clank, Bloodborne, GT7 if that drops on PS4, WiLD too, Rime.
Metal Gear, Batman Arkham Knight are must have 3rd party games for me too.

The Legend of Zelda U, Starfox, Splatoon, those are absolute must haves for me, Devil's Third is starting to intrigue me too.

Probably Battlefield Hardline for the replayability, there will be alot of better games next year but not any ones that are going to be more replayable imo

The Witcher 3, easily.
