“No one gives a crap about Steve” is that why many people who ask for him genuinely want him specifically and not just a stage and whatever, and would be disappointed if he was less than a fighter even if it’d be better than nothing? Is that why there’s a lot of fan art for him, Alex, and others? There are Minecraft fans who don’t care about him, but most people either like him or don’t give a crap either way. He wouldn’t be “Byleth-tier” as far as I know, as the people who spout rude hateful stuff about him are a clear minority. Steve is used as a character in some stuff, and people like me have grown attached to him due to liking his design and seeing him as the face or an important face of the game they love.
All you have to do is look at the Codename Craft twitter account to see that the number of people who want Steve specifically are getting up there with other characters - one of their previous accounts before trolls attacked them even had double their current followers and maybe even nearly triple. There’s even a YouTube video about an animated Steve moveset for Smash that doesn’t mention Minecraft itself (so you either have to get it recommended to you or search for it specifically) with over 180k likes and 2 million views. Saying “few people want Steve specifically” is blatantly false.
Sorry, you misunderstand, and I probably should have been more specific: People want a "playable Minecraft character", but the best they have is Steve (or Alex). Minecraft has no real characters, just an avatar that grunts when injured. Steve (and by extension, Alex) has no personality, no characteristics, no anything. They're the blandest of the bland, boring, blank-slate characters, that's the best they're gonna get. If there was an actual character that talked and did something more, you bet your ass people would want them over Steve.
FTR: This isn't me hating on Steve/Minecraft, not at all, I actually enjoy Minecraft. It's me pointing out the fact that Steve is barely a character, and sadly the *only* character (with Alex as an obvious alt) that you're gonna get if you want a playable Minecraft character.
That said, he would be somewhere in the Terry-Byleth area for the general Smash player, but he would probably bring in a ton of new players. To me personally, he'd be a Terry-level character.
Banjo has the least amount of views of every presentation
That's irrelevant. Many people actually watched the E3 livestream. Significantly more were tuned in towards the end than the exact beginning, or they just watched the entire E3 video. That would naturally mean that they didn't need to then watch the reveal video.
Without bothering to look, I'd be willing to bet Byleth and Joker were the "most watched" videos since not nearly as many people watched VGA 2018 compared to E3 2019 or even the Q3 2019 direct, and to have seen Byleth's reveal, you'd have watched the Sakurai video for them.
From both a competitive and observable metric perspective, Joker seems to be the most popular pass character.
The former is irrelevant because he's the highest tier of any of the DLC characters. The latter is very biased in favor of him because of literally what I just said: Not nearly as many people watched VGA 2018 compared to people who watched E3 (or even Q3 Direct) 2019. Without even bothering to look, I'll bet you that Byleth was #2, Terry was #3, Hero was #4, and Banjo was #5, based on people who watched those events live (and therefore wouldn't need to watch the videos).
