So I took the plunge and pre-ordered this for my 3DS. I'm a bit miffed that there is no online play with the 3DS version, only local co-op (or online for the Wii U version). There's a way to circumvent it if you have a Wii U and the Wii U version, but I have neither and don't plan to get them. Either way, I still enjoy single player mode for these games. Anyone play the demo yet or any of the other games?
