I offered a bunch of choices but let's not kid ourselves. For the top spot, I think it's a 3 way fight between Battlegrounds, Mario and Zelda but really a 2 way fight because Mario will be dismissed for just being Mario.
A lot of the staff is hot on PUBG so for sure it's one of the top contenders. The thing is, it didn't hook everyone and some of them haven't really touch it. Also, if people wanted to argue against it, there are plenty of ammunition with its name on it.
Jeff isn't that hot on Zelda but can he, alone, convince everyone it's not the GOTY? I don't think so. Besides most of the staff's love of it, it contributed significantly to Nintendo's risky Switch bet. My BOLD prediction: Giant Bomb's Game of the Year 2017: The Legend of Zelda: Breath of the Wild.
