It’s just not something I have experience with. Even my wife, who likes public validation, also prefers to role play in games.
But that’s the great thing about most RPGs, they have options to get whatever character model you want. So whether I understand people wanting to play as themselves or not is irrelevant. You can make your character look like yourself, I can make my character look random, and a trans person can make their character look like they see themselves. How I choose to make my character look has no impact on anyone else’s experience.
