Super Mario Maker.

MGS V will win. But for me it is between

The Witcher 3
Batman AK
Splatoon
MGS V
Bloodborne
Yoshi WW

Also Im confident about Xenoblade Chronicles X to make the cut

Bloodborne for me. Love the visual design and world and breaking down enemies. Eclipses the Souls series for me.

Batman: Arkham Knight for me.

SPLATOOOOOOON!!!!! it really is a superb game.

Its a good game, and at first I would agree. But too much "tankmobile" really made it a bit of a chore in the end :(

Super Mario Maker

Yeah, the batmobile tank mode was definitely devisive. I have certainly heard that complaint a great deal and can understand it. I was worried about it myself at first because I just normally do not like driving modes in my action adventure games. In the end, though, I enjoyed those parts of the game. A little less tank mode would have probably been better for most, especially towards the end.  

Witcher 3 still so far. But MGSV is also seriously impressive.
