I think the gamecube, really. I enjoyed the Wii games without a doubt, but considering it had backwards capability, I played those games on the Wii itself probably just as much than the Wii games. Plus nostalgia. I'd consider "starting over" on a few games, but I'd need a controller, cables, and the games again. I mean the only games I really played extensively for the Wii was Smash Bros and Mario Kart with my brothers.
Do you plan on buying any new video games in the coming year?
