I would like to buy Virtual Console titles once and play them on every future device (connected with NNID). The transition from Wii to WiiU with VC-titles was horrible in my opinion.
I want backwards compatibility. That's very important for me. I didn't bought PS3 back then, because they dropped BC before european release. I bought it only a year ago.
I want the continuation of MIiverse - this is great.
