Would anyone in good faith, with only two options “Stereotypical Brodude or Fashion Magazine Cover Girl”, is going to play the former with she/her or the latter with he/him?
Not sure what you mean by “good faith” here, but I can assure you there are some he/him dudebros that play female characters bc if you’re gonna be staring at someone in 3rd person the entire game it might as well be someone attractive to you.
Also it’s perhaps a minority of gamers, but people with fewer identity issues don’t need to see themselves as a self insert for their character, so why not play someone totally different from you?
