Well, people do realize that Yoshi is also on the casual side, right? As much as I like woolly world, you can tell its made for kids/casuals by how braindead easy it is, and how the game's aesthetic is.

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.
