I find it strange that people could read pieces like Leigh's and get out if it that "gamers have won" like Chris Kluwe did. I saw it as a frustrated tirade at the group of gamers who were perpetuating "thezoepost" harassment and the chasing of Anita Sarkeesian from her home. There's a way of telling people that the market for games is broader than what people perceive to be "Gamers" without resorting to referring to those people as "obtuse shitslingers" which Leigh failed to do.
If she wanted to encourage people to create games for emerging markets, there's no reason to focus on established markets, she should spend that energy describing those people who can make games that try to reach outside of the traditional demographic for video games. She can bring up Nintendo's success with the Wii and the success of mobile games to engage an entirely new audience as examples of how to reach out to people who wouldn't even know they were "gamers".
Instead she relied on old stereotypes in an attempt to weaponize the word "gamer" to mean something that to most people who would use that word, it doesn't. Most who use it, as I do, would probably agree more with Greg Tito's idea that a gamer is one who plays games as a primary hobby and is interested in their history, creation and makers. People might play Journey, but a "gamer" might dig around and find out who Jenova Chen is, that Austin Wintory was nominated for an Academy Award, that Kellee Santiago went to work for Ouya, and that Journey was preceded by Flow and Flower.
I mean, I get that she's frustrated, and she's probably seen more scary shit than most of us can even comprehend, but Leigh did herself a disservice by trying to equate the actions of some sociopaths to a larger group than she realized. Just because her friends don't like to use the word, doesn't mean everyone's like her friends.
