Why would they?

There's a lot of reasons someone might want to play a female character. In Fallout 4 and 2077 because the female voice actor is hands down better. Sometimes the gear is cooler looking. Maybe you just want to. Even if you usually play as a male maybe it's your second playthrough and you want to try both protagonists.

Consequently, I feel like if you're playing as a female on an online game and the character creator sliders are generous so you make them fat assed and physic based enormous breasts and then run around being a stereotype you're likely NOT going to be popular among female gamers.
