IGN - Nintendo addresses the idea of bringing more Wii U games to Switch, jokes about Mother 3

Coming from Reggie Fils-Aime...

“The internal conversations we have is that on one hand, the development teams would love to showcase their content to a wider base, and certainly in short order the install base on Nintendo Switch will be larger than the install base we ended with Wii U. So there is that opportunity. What also drives the discussion, though is ‘what more will there be?’ Meaning, let’s take Mario Kart 8 Deluxe as an example. It needed to be the definitive version of that software for the consumer to be as excited as they are. Pokken Tournament DX with the additional fighters, the additional Pokemon, that was important for it to be an element of the game. What we are internally resisting is just a pure port, versus thinking about how not only do we showcase a game to a wider audience, but how do we make sure that there’s something more? So it’s an active discussion.

Look, in the end, fill in your favorite franchise here. It comes down to how do we do something more? How do we do something unique? How do we take a franchise and make it vibrant with more and [reach] more people? That’s the focus and so, even when you look at something like Metroid: Samus Returns, it’s not a pure remake. We’ve added more, we’ve added elements to expand the Metroid franchise and to make it more accessible and more vibrant. That’s how we think about our different franchises and different IP. So when one of our developers has an idea – and again, fill in your favorite franchise here -- to take it and make it more vibrant, that’s when it will come to one of our platforms.”

Reggie was also asked about Mother 3, to which he didn't really have any news to share.

“I thought I was going to make it a day at E3 without being asked about Mother 3."
