My favorite game of the year is THE LEGEND OF ZELDA BREATH OF THE WILD
+ Developers Weigh In On The Legend Of Zelda: Breath Of The Wild's Brilliance
Additionally I can't say enough good things about how great PREY is, one of the few games that actually propelled me to beat it.
Another stellar game from the same studio that came out this year: Dishonored: Death of the Outsider
This year seemed to be quite the year for archery in games....
