I think people are, willfully or otherwise, ignoring the point being made and focusing on other aspects of the argument, and that's that there is a very notable pushback against first party additions that aren't either Switch-or-newer or Waluigi and sometimes Isaac.
To illustrate, I'll use a character as an example. In particular, a character that was offhandedly thrown under the bus a page and a half ago with no pushback from anyone else: Starfy. Good old Starfy is a character that best illustrates what I'm talking about: a character with modest popularity from a fairly obscure Nintendo franchise, who was disconfirmed for Ultimate early on with the reveal of his Assist Trophy. He didn't have Waluigi level popularity, since very few characters do, so discussion died down after the Assist was shown off. That's expected. It's the natural cycle.
So what are Starfy fans to do? They were told, after all, that Starfy's odds for Ultimate were done and dusted, and they were. They were told he didn't fit Nintendo's DLC plans due to his series being on extended hiatus, and due to his role in the base game. And that was right. So what did people say? "Wait until next game, when the board is reset." And now the board is reset.
So why are people still acting like talking about characters like Starfy is a fruitless endeavor not worthy of discussion? Why are we still using DLC "rules" for an as-of-yet unannounced base game, when characters like him have their best shot?
Yes, you can say "people can still talk about those kinds of characters! Nobody is stopping them!" But that's missing the point. Yes, anybody can scream into the void. But if nobody engages with it, what's the point? Why talk about characters you'd want when it's blatantly clear most of the thread won't even entertain the possibility of those characters getting in in the future?
Instead, at best, you get people imparting their sagely knowledge almost patronizingly, like a Nick Offerman-looking father figure getting down on his knee, putting his hand on Little Timmy's shoulder, and telling him, "Well, sport...the sad truth is that Starfy didn't go to a farm upstate, he's just irrelevant. And as such, we don't want to waste our time talking about him."
And like, okay? So was Banjo. And I can hear you say, "but Banjo had fan demand." And you know why he did? Besides Phil Spencer, I mean. It's because people were allowed to talk about him. And people engaged with the conversation. But by not engaging in discussions about other characters who may be seen as obscure, you're also killing the chance of them ever getting a fanbase that large pre-emptively.
Before anyone tries to tell me I'm against third parties, third party additions are legitimately some of my favorite additions in Smash. When Sonic and Snake were added to Brawl, I was fascinated by what could be done in future games. Mega Man and Pac-Man were some of my biggest requests for Smash 4, albeit with the caveat that Pac not be his Ghostly Adventures design. When Ryu was found in the files, I was ecstatic. How cool was that? Ryu, the fighting game character, was going to be in Smash! And Cloud, the eternal never-ever, finally getting in felt so damn surreal. When Simon got leaked for Ultimate, I was super hyped, and hoped they'd use his Conan-like look. And then he did! And out of Ultimate's eleven Challenger Packs? Out of my top six (Terry, Byleth, Min Min, Steve, Sephiroth, Sora), four were third party! A whole two thirds! And even now, I would love to see the likes of Lara Croft, Frogger, Phoenix Wright, Maxwell, and (managerial changes in the future assumed) Ezio and Crash!
But as someone who also wants some fairly under the radar first parties, it's legitimately disheartening to see characters I want to see written off as "irrelevant," or "not even has-beens, but never-was-es," or "characters only diehard Nintendo nerds who spend too much time online would know even exist." If I had a dollar for every time I've seen characters like these dismissed because "all of the important Nintendo characters are already here," I'd have enough money to financially ensure the future of all of their franchises singlehandedly. It often feels that you can't try to raise support for a character unless they'd make Twitter collectively soil its pants in hype.
And dismissing these fanbases entirely as internet echo chambers just makes it a game of who can talk the loudest and control the conversation. Isaac, one of these characters who's better off, gets talked about a lot, and Golden Sun etched itself into a lot of people's hearts for being a solid RPG on a Nintendo console, a rarity for its day. When Starfy got into Super Mario Maker six or so years ago, people came out of the woodwork saying how happy they were that Nintendo remembered him. People talk about wanting genre diversity, but ignore that Dillon might just be one of the best possible characters to represent the tower defense genre. Sin and Punishment just got added to NSO, and will likely reach more people now than it ever did before, even with Nintendo's headass pricing. Takamaru's biggest obstacle for inclusion, being Japan only, is no longer the case. Sukapon got a second lease on life, getting his pink, circular foot in the door as an Assist.
And those are just the ones that get talked about somewhat often! You know what game I always, without fail, see brought up from fans of games like Ace Attorney and the Nonary Games? A game that Nintendo owns but you never see Smash fans talk about? Hotel Dusk. Despite Kyle Hyde having a trophy in Brawl (an animated one at that!) and a spirit in Ultimate, and despite Hotel Dusk being a cult classic, the game doesn't get discussed in the context of Smash, showing that yes, blind spots exist among those who look at first parties, as well. So many ideas can get tossed around and people can learn new things about games they didn't know about. It's nice. But all too often it feels like the conversation gets neutered before it can happen because people have already made up their mind. And often, it's simply because it's a Nintendo character that isn't new or Waluigi.
Because hot damn does it suck. Like when Maximilian Dood's reaction to the Byleth presentation is an uninterested "is this a waifu game" jab. Or when Honest Trailers had that god awful "Now they're scraping the bottom of the barrel. Who knew who Shulk was before this game? Congrats, you're now Japanese," which was frankly infuriating. Like Jesus Christ just use Google you unfunny voice over man. Look at Project Rainfall. It's not hard. Well joke's on you, now your channel is owned by Fandom and people rightfully hate it. Anyway.
Being pushed aside with the Smash Speculation Forum equivalent of "be quiet, the adults are talking" ****ing sucks, and I'll no longer pretend that it doesn't.
So that was my rant. I apologize to Nick Offerman on the off chance he's here, because damn it you never know.
