Well, Christmas is getting closer, and I need to think about a good game for either the Wii or DS. Can you suggest what's new in there for me?
I read that NSMB Wii was "satisfying" from someone on Kotaku. Animal Crossing got boring, so I would not recommend getting that if you haven't already. WarioWare Smooth Moves is fun for small parties. Mario Kart Wii seems like it would be more suiting though, though I haven't picked it up in a few months.
WarioWare D.I.Y. is also coming out around the corner. If you're on the piratey side, I would recommend an M3DS Real or some other flash card (check GBAtemp for the details for which one would suit you better. I think that the original R4DS isn't supported anymore, but it may be one of the better ones for homebrew.) Maybe an IOU for the North American release of HeartGold/SoulSilver?
NSMBWii is definitely enjoyable. I also highly recommend getting a couple of points cards...phenomenal titles have been released lately.
