So
Overwatch (GOTY, Design, Action [Doom robbed] and Online) &
Uncharted 4 (Technical, Story, Adventure and Animation) with 4 wins each.
Inside (Direction, Art and Sprite) with 3.
Pokemon Sun and Moon, Civilization VI, Steep,
Dark Souls III, Forza Horizon 3, Street Fighter V, Ratchet & Clank,
The Last Guardian, SUPERHOT VR, Battlefield 1,
Doom, Pokemon Go and Eagle Flight with 1 win each.
6 of them are in the top 10 GAF GOTYs.
I think the awards were fairly handed. Doom should've won Action.
Honestly 2016 was a great year, so many GOTY worthy games.
