Here are some facts: Women play video games (almost 50% of all video games and a third of PC and console games!). Women have money to spend on video games. Women would like to see themselves represented as playable characters—not just sexualized prizes—in video games. Playing a female character in a video game, if you are a male-identified person, will not cause you to suddenly extrude an armored bra out of your skin and start tacking Eat Pray Love quotes on your intention board (see: all the girl gamers who've managed to play mostly male characters for decades without transforming into human ballsacks and making 25% more money at work). And players of all genders reportedly enjoy "the option to be able to play as anything other than the generic brooding white guy hero."
So, despite all those facts, why are playable female characters still such a rarity (and treated like an impossibility)?
