Nintendo: Mario, Pikachu, Link, Donkey Kong. So I agree with OP's list.

Sony: Mazda Miata, Drake, Kratos, Ratchet. (Spiderman/Aloy/Ellie/etc don't have enough history to be considered to get on there, IMO)

Microsoft: Chief, Fenix, Ferrari 458. (Honestly I don't there is a fourth one that deserves to be there)

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.
