No, I'm not going to put this year. Though 2013 didn't exactly have a lot of time with the new generation full stop.
For me, easily 2016:
Doom and Uncharted 4 are two of the best single-player titles of the generation so far: beautiful, epic adventures of mad spectacle and ...well, Uncharted bore some epic drama.
But game of the year? Overwatch. I'd call it this generation's Halo or Left 4 Dead for the many hours of multiplayer shenanigans I've enjoyed on it. Absolutely fantastic stuff.
You?

2015 had Witcher 3, Just Cause 3, Fallout 4, life is strange, etc. It was a really good year for gaming. Especially considering it wasn't plagued with microtransactions, like the only other year on this list that came close.
