Even if the Wii brand met an unfortunate demise, it's a shame that Miis seem to be downplayed ever since. I loved the idea and hoped they would persist into future consoles… but not like this. I keep imagining ways Miis could be enhanced, like using outfits as a systemwide achievement system, or even just adding facial features included in other avatar systems like Apple's Memoji.
At the same time, Miis really don't work in series like
Animal Crossing, much less
Pokémon. In these cases, I think they should be used to set the initial appearance of customizable player characters like Villagers, Inklings, and Pokémon Trainers, providing a personalized starting point for character creation screens. This is basically already
how NPCs were created in
The Legend of Zelda: Breath of the Wild. (Mind, that doesn't support all Mii customization options, and this adaptation idea wouldn't necessarily have to, either.) Elsewhere, with this new level of graphical quality, maybe we could've seen stylization of Miis to make them fit in better in certain titles, like a subtle wooden texture to make them look more like kokeshi, rather than abstract fleshy humanoids (or hamburger homunculi) that look inconsistent with human characters in most series.
I can dream! At least the situation isn't dire for Miis. They're still being carried over across consoles, they're still getting dedicated games, and it seems like Nintendo received the backlash over Sportsmates in
Nintendo Switch Sports given the big deal they made of adding Matt.
