Both zelda and halo smell like old people.  I can understand why some people like those games a lot but can they be considered for GOTY? I think not. 

According to GOTY Blog:

Wind Waker came in second after Knights of the Old Republic
Twilight Princess came in third after Oblivion and Gears of War
Skyward Sword came in a distant fifth place after Skyrim, Portal 2, Arkham City and Uncharted 3

Every main seires Zelda since Majora's Mask has failed to top the GOTY awards.

There are both endogenous and exogenous reasons why it might not. First is simply that Nintendo doesn't quite deliver, second is that Zelda U is everything anyone ever wanted from a Zelda game, but Witcher 3, Uncharted 4, Halo 5, or whoever else is that much better still. Despite my Nintendo bias, i know that the consensus opinion could easily swing away.

Or be a case where there is no clear cut winner.

i have a lot of doubts with names... Bloodborne, Uncharted, The Witcher, Metal Gear Solid V the Phantom Pain.

would like to add Halo but i havent seen enough of it to be honest

As plenty others have said, there's many, many good games out next year. More than in any previous year for quite a while actually. No game has this on lock yet, but considering how these things usually go I'll say Zelda's chances aren't the best of the bunch.

Metal Gear Solid, Uncharted, The Witcher, Batman and Zelda should be the ones with the most chance. I don't think Halo will take it. We'll see.

Personally, of course Zelda will be my game of the year, I can say that already. It's Zelda, that goes by default! Uncharted would most likely have been it if it released in any other year though.

No, Xenoblade Cross would be the GOTY 2015…....…. At least on Nintendo consoles XD.

In a year with such steep competition, and with it likely to not have voice acting and get lambasted for it, I suspect it will not be most critic's choice for GOTY.

As for me, my GOTY will probably be Xenoblade Chronicles X.

My bad then. Wind waker should have made it though.

No doubt. The best franchise ever and the one with the most quality ever.
