Im thinking of getting a wii sometime soon.

[meteora]

I would buy
Zelda (great)
Exite Truck (a lot of fun, but get and SD card at the same time, because the music in the is not that good)
RE4 (if you didn't try it last gen, you need to now)
Super Paper Mario
and maybe Scarface or Godfather, if you want a sandbox game.
