There is Brawl, Mario Galaxy, Mario Kart Wii, Wario Land Shake, Megaman 9, Dr. Mario, and the Homebrew Channel, which lets you use better emulators than the VC and such. So, yes, buy a Wii, right now.
Wii fails to facilitate anyone who wants to do some serious gaming, but if you're a fan of novelty and new things don't wear easily for you, go for it.
For the VC and animal crossing..And brawl and mario kart..And mario galaxy, Yes.
