Better customization options. I remember a Poke-tuber talking about watching his GF play Pokemon sun and moon and being like “wait you got a skirt? why don’t I have one” and realizing that it was not so much that he wanted his character to have a skirt, but that he was uninterested in having like 4 options for pants that only changed in slight ways. You usually get shorts and pants, maybe a jeans option. As opposed to shorts, pants, tights, skirt, mini-skirt, and dress just for starters in a lot of games.

Also so many games have male protagonists, and for games with an option the male one rarely matches the uniqueness or skill of a Nolan North or Roger Craig Smith, usually they feel generic even if not bad, but due to the lack of female protags their voices really get to shine even when just one of two choices.

Best example is assassins creed Odyssey. Alexios’ voice is made fun of a lot and while it is not godawful, it feels like less of a full performance of a unique character, whereas Kassandra’s VA won awards and it so beloved. She gave a performance that MADE that game and sold Kassandra as a full character. Now Kassandra was supposed to be the only protag so that makes the comparison a bit unfair, but you get my point

edit: Shepard is another good example. one performance is just way WAY better than the other
