Eternal Darkness or Earthbound would help round out their core offerings. I think Golden Sun would be good too to further expand their RPG offerings.
But frankly Nintendo also needs to just better handle some of their more core gamer IP. Frankly, I don't get what their deal is with F-Zero, Star Fox, and Paper Mario. In every other great franchise they always experiment but with level design, mechanics, etc with few exceptions. But these three they feel that unless they can reinvent them they've failed miserably, all the while ignoring obvious possible improvements and expansions they could make. It's really bizarre.
