There was one. And Undertale won it.

I don't think it's the best game ever, but it was certainly my personal GOTY, and I can see why people love it so much. I can understand that it's not for everyone, but I think it's the most unique and well-executed game this year. A lot of creativity went into it, and all the different aspects of the game were executed nearly flawlessly. Not many games manage that.
No doubt games like Witcher 3 and Fallout 4 are great games too, but they aren't really unique, they are just new additions to the giant pile that is mainstream AAA games. They're all the same to me. Which, if you like that sort of thing, is probably a good thing. They don't stand out like Undertale does though.
For me "best game ever" would probably be OoT. And it nearly won, too.
