^Hmm I think that's the case with Path but I'm not sure about that with most gacha games. As someone who always plays female and non-gendered/non-binary characters over male ones, I feel from what I've seen with a lot gacha fandoms online is that lot of people pick male characters / label male gender automatically to non-gendered/non-binary characters. That's something that I clash with when it comes to the Arknights fandom as one example, for me the Doctor is non-gendered/non-binary, though if I were to pick male or female I'd go with a female Doctor, however the average person in the fandom calls the Doctor he/him and automatically labels the character as male.
With FGO most people treat the "canon" protagonist as the male one, and even the devs throw the female protagonist under the bus unfortunately. Same with Fate anime adaptions, if there's a male or female protag they're going to go with the male protag and treat him like the canon protag. Which sucks imo, and I'd love to see more adaptions with the varied female protagonists in the franchise.
I worry about that with the Genshin anime supposedly still in the works, I really would love for them to do Lumine as the protag...but I worry that Aether will be picked instead. I especially worry because there's a whole part of gacha and related fandoms that play the male protag and are weird about it for varied reasons. Probably not the place to go into it further, so I'll leave at that for the moment.
