Hotseat (couch) Mario or similar

[Fragems]

You could get a Retron and play through the Wario/Mario games on the the Game Boy or you could just emulate if you have a PC/TV setup.

Wario Land Shake It on the Wii is also really good.

We have a couple of modded xboxes hooked up and I have a gamecube gameboy player as well. We already more than most other franchises pass the controller back and forth on the classic marios. We want to play mario type games co-op. It seems that a WiiU is the answer so I'll get one sometime this month, tho I'd still like to hear any other suggestions.
