Which 3rd party ports would be most succesful with the Nintendo audience?

[fleischr]

I think nearly all Japanense games are a given (Final Fantasy, Tekken)

As for the western side of things: pretty much anything by Activision-Blizzard. Overwatch feels very Nintendo-ish. Destiny could have an interesting new life on a Nintendo platform, especially with Miiverse involved. And a Diablo III port could still work out okay too. And like it or not, a new Nintendo home console *needs* Call of Duty to be relevant to the masses.
