Since the topic is still hot, I'd like to bring this up again.
A game with a healthy balance of male and female characters tends to be more engaging and relatable for a broader audience. Balanced representation allows players of all backgrounds to find characters they identify with, fostering emotional investment and inclusivity without alienating any group. It also opens the door to richer storytelling contrasting personalities, perspectives, and dynamics that reflect real human diversity.
By contrast, an all-female cast can sometimes limit narrative range and audience connection. In most cases, balance simply makes the world feel more authentic and authenticity almost always makes for a better game.
