Now I do personally feel like I'm the resident forum video game expert and I'm not really picking up your angle with this.
I do agree that there aren't many anthro/furry/non-human characters in video games, but that's not something to take offence over.
You getting upset over the Smash Bros DLC makes me a bit sad, because they're awesome characters from awesome games and Nintendo choosing to release them in response to what the majority of fans (Including myself) would like to see and including a few surprises that just surprised everyone (CLOUD STRIFE!!!!). All in all, They're not going to release more pokemon characters because of poken tournament and there already being an impressive roster and Banjo is never happening because of Microsoft owning him.
Animal crossing characters would be amazing though and I can get behind that. Even Wolf would be a welcome return, but there's no reason to abandon a game because of new characters all being "human". I can't actually come up with a good comparison because of how much the reason throws me off.
A reason I can think of why there aren't many anthro/furry/non-human characters in modern media is for the same reason there aren't many 2D cartoons any more - It's seen as childish (not that I agree with this - anthro/non-human/whatever characters can be seriously badass).
I also think there isn't much of an appeal for such characters outside of the fandom and children, because it's easier to relate with and invest yourself into a human character. You look at them and think "Woah, I'm human too! I can bee as cool as that guy!" or at least I'm sure how the masses see this.
I'm also not sure how by default a character that is human is automatically "lol humens are the best" in the cases of the new smash bros DLC characters because of their franchises (Side note: My favourite is the Duck Hunt Duo). Arguably, half the smash roster is already non-human.
Rounding off though, while it obviously is a problem for you, I just can't imagine anyone else having the problem. New characters of any kind is a new way to play and brings in it's own enjoyment. I recommend looking for what is enjoyable instead of what won't be and you'll have way more fun. All else fails, check out gamingfurever.com for a database of furry games.
My problem is the three new characters are, honestly, pretty much the same character. Corrin is yet another character from an over-represented franchise, two of them are sword-wielders, and Bayonetta is from an M-rated game. Couldn't they have at least given us one more non-human? Or at the very least a cartoony human? And even if you don't think I should be offended, nothing is going to make me spend ten 18 or so bucks on characters I strongly dislike. Not just because they're human, but because they're typical "Mature" humans, two of which are from "hoomans are absolute gud" games.
I never play as Villager, ever. The franchise has hundreds of animals, and the only playable is the one human. And frankly, I was already bored of this game, and was counting on at least one of the characters being interesting. Instead, and I'm sorry, but I still feel kind of insulted that we get three "edgy" humans. If they bring back Wolf as a surprise, I might go back, but otherwise I have no interest in playing the game any further. To reiterate, I was already bored of the game. The new characters just make me want to play it less. Yes, I know they're optional, but the fact they exist in the game at all... I'm sorry if I sound offensive, but this is my honest opinion. I can't help but feel angry about it. Even with explanations, I still feel angry about it.
If there was a way to make people realize that anthro characters aren't childish. I'm dying to see more anthro games. And I'm sorry, but every time I see a human character, I usually think either "whatever" or "ugh, another one of THESE kind of characters." Usually the later with typical demon/zombie/alien hunter cliche humans in games usually devoid of originality or personality. Anthro characters are different, unique and interesting, and that's why I like them.
"hoomans are absolute gud" games means ONLY humans can be good. Everything else, no matter how innocuous, be it bunnies or squirrels, are evil. The only "non-human" goodguys allowed are elves, dwarves, robots with human faces and anatomy, and basically ANYTHING that looks almost exactly like a human. But once a character stops looking anything like a human, they can no longer be good. You can put wings, cat ears, and tails on a human, but they're still a human.
Actually, a lot of furries have the same problem. I'm not the only one, and I'm sure there are others on this forum that do kind of feel the same way. I mean come on, even YOU have to admit you would buy a really good game if it had anthros as the main character. Plus, how many games on that site are any good. I've been really looking forward to games like Yooka-Laylee and Clive and Wrench, but sometimes it feels like anthro games are cursed to suck, so I wouldn't be surprised if these games end up sucking.
I know it feels like I'm too negative, but deep down I can't help but feel negative. I'm probably a bad person because of it.
