While it would be nice, but realistically not possible due to it's branding and considering the very base foundation and establishment of the game... I'll let it subside and choose to not let it bother me too much or at all. All that matters is that they put more represent-able female characters in the game to play as and I'll be content.
That's actually another issue entirely. As of now, Smash Ultimate's percentage of female fighters (who are women by default) is at 20.513%. For reference, that's only better than Marvel vs. Capcom: Infinite (16.667%) & Dragon Ball FighterZ (8.333%).
Everyone getting heated over this is falling right for it. That's the reaction this thread was made to give you. Nobody gives a shit about the name of Smash Bros when there are actual representation issues in games, including Smash itself.
I almost said no, and then I wondered how a Smash game simply called "Smash" would come off to me, especially if it was a massive gaming event and reveal like Ultimate, and it occurred to me that I'd actually be totally ok with that.
Everyone who I follow in podcasts/media and all my IRL friends just call it "smash" so clearly "Bros" isn't an important part of the name. It can be done if there's a will, but gAmErS will react strongly to it
