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?

Each year always seems like it's going to be "the year" of gaming but it never is and it won't be until we have some genuinely great games that are something to really look forward to.
