Nominations:
God of War
Red Dead Redemption II
Monster Hunter World
Spiderman
Forza Horizon 4
And without a doubt one of the first two will win it.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
