I told a friend of mine who plays battlefield that you should try out splatoon, and his answer was "isn't that a kids game?" I would assume many cod and Battlefield fans won't really give it chance since it looks cartoonish, making them go straight for the conclusion that it's a kids game.
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.
