If Nintendo went Third-Party, what games would you buy from them?

[TheWPCTraveler]

Considering how many people want Nintendo to go third-party, I think it's fair to ask what Nintendo can expect from them when they do so. And, for those who want Nintendo to stay first-party, join in as well.

This is assuming Nintendo continues to produce titles that are the same quality as when they are first-party, even after the shift from PowerPC to x64.

Edit: I know this is a very late edit, but as can be seen from the title, I meant an "if" to take the place of "when."
