I can see them only caring about drawing in more fans. I guess I’m just interpreting the whole “demographics” thing wrong.
However, they could very well do the same with Minecraft. As said by

, it’s now a decade old, so really I shouldn’t have called it even “newer” I guess, as it has been greatly established and has plenty of fans young and old, also following Nintendo’s idea of broadening demographics with the Smash DLC; though I guess since Minecraft is on the Switch, they kinda already had that, however Smash could potentially attract a lot more than just a port.
It’s true: Sakurai may not find Steve to be realizable, but I don’t really like this kind of discussion. Fans have already made nice movesets and animations for Steve, even while keeping his stiff limbs, and I have no doubt Sakurai could as well. I really believe Banjo-Kazooie was Nintendo’s way of pleasing many longtime fans, making a whole lot of us happy, and not much (if anything) more than that. Steve and Minecraft could very well come next game; you could also say Sakurai will put more thought into this stuff, based on how he changed his mind with Villager, Pac-Man, and the Miis.
