Is Playerunknown Battlegrounds a GOTY contender?

[SegataSanshiro]

It's early Access so no. If it was a final release then yes but would at best win best multiplayer but not GOTY.

Also it's contending with

Zelda Breath of the Wild
Horizon Zero Dawn
Mario Odyssey (likely)
Persona 5
NieR Automata
Splatoon 2
