Do people really care what gender the MC is? I just role play as whatever gender the character is.
If I’m playing Tomb Raider, I am Laura Croft. If I play GTA, I’m CJ or Trevor or whatever. If I’m given a choice, I’ll sometimes look up if the gender matters (e.g. in Mount and Blade it can impact relations), and otherwise just pick randomly. When there’s a character creation screen, I usually randomize it a few times and get into the game.
I wouldn’t mind role playing as a gay or trans person, though I’d be a little worried about the content because I’m not looking for anything with relationships, I want to wreck monsters and solve puzzles.
