No matter to me. I don't have a Wii U. Still, it seems interesting, and I do know some people who have a Wii U and I would like them to try this. It seems that, from what I could gather on SmileBoom's Japanese website, PetitCom BIG (SmileBASIC BIG) costs 3 times what SmileBASIC 3DS (PetitComputer3) costs. But I'm seeing advantages, like multiplayer games being much easier to make. That sounds cool
