Not weird at all. You have to really love Nintendo to get Smash and let all the callbacks wash over you (theres nothing there for me), and Bayonetta has even less widespread appeal being a hyper niche combo action game. Thus for review at the publications, those games would have been thrown to the "Nintendo fan" in the office, and "the combo action nutter", who are occasionally the same person, sometimes not, and consequently 2 out of what... a 7 or 8 person review team? What happens then when the 6 or 7 other people all agree on another game? Thats whats tended to happen. I think people would have narrowed their eyes into blindness if Velocity 2X was GAF's GOTY for instance using the Metacritic argument, even though I enjoyed that game.
I am happy Bayo 2 is up there, its a good game, just didn't satisfy me in a way previous Platinum titles have and I felt I played things that made more impact on me throughout the year. 2014 is the year I was thoroughly disappointed in a Bungie title and a goddam Dark Souls game, so all in all it was a pretty fucking weird one. 2015 is going to be a fucking bare knuckle fist fight for the ages though (mainly because tons of shit slipped from 2014).
