The conflict you’ve set up here is a false one. You’re suggesting we should get upset about the lack of women developers and sexism in the industry “instead” of the lack of women characters, as though those two things are mutually exclusive and/or at odds, when in fact they are inextricably linked.
You see, there is a vicious cycle: most game developers are men; so they make games they like, which are games men and boys like; so it’s mostly men and boys who buy the games; so marketing departments decide that men and boys are the only audience; so games are exclusively marketed to men and boys; so women get the message that games are not made for them; so women don’t buy games; which makes the marketing a self-fulfilling prophecy; so women are excluded even further; men in the industry feel secure and superior; this creates a hostile atmosphere towards women; so women see an industry that doesn’t want them, and they don’t want to be a part of it either; and so most developers remain men; and the cycle repeats ad infinitum.
So you see, the sexism directed at women in the industry is both a result of a lack of female developers and also a cause. A lack of well-written female characters is both a result of a lack of female developers and also a cause. So setting up this as a situation where we’re allowed to care about one of these things but not the other is counterproductive. Do I want more well-written women characters in games? Of course. But do I also want more women characters? Yes. There’s no conflict there; I want both.
Ultimately what I want is a complete change, a complete breakdown of the ugly cycle I outlined above. I want an industry that doesn’t treat women like garbage. I want an industry whose population in some way mirrors that of society at large. And I want marketers to understand that women play games, and to stop devoting all of their efforts to pretending they don’t. I think that a greater effort towards diversity in characters can be one important component to this breakdown. I think it could be both result and cause of a new direction in the industry, and therefore it is an important thing to strive towards and advocate for.
