I guess I would be a bit more assertive in releasing VC games on a consistent basis. I would have to make deals with third-parties in order to release games like Final Fantasy, Metal Gear, Dragon Warrior, Castlevania (that have yet released), etc.
As some mentioned, Mother 3 would be great. However, I think I would have to ask Itoi for permission since he is the one who owns the rights to their series and he even was the one, himself, who announced Earthbound Beginnings for VC at E3.
Other Wii games that haven't released in the US such as Captain Rainbow or Fatal Frame would be great as well. I guess it just depends on what I can get in terms of deals from other companies.
