I brought a nintendo wii last week, what games do ya suggest i buy

[Khuutra]

Zelda: Twilight Princess
Metroid Prime 3
Mario Galaxy

Those three games one hundred percent need to be in your list if you like single-player games (and Mario still works if you like co-op). There can be no argument brooked here!

After you get through those three, you can worry about other stuff.
