This is kind of Leigh's bag, isn't it? She invades a cultural space and then belittles and mocks the participants all the while pining for said culture to bend itself around her wants and desires.
I mean, she's been doing this for as long as I've known about her, which is over five years at least.
It is beyond ridiculous to accuse Leigh Alexander of invading a cultural space. As you said yourself, she's been writing about games for over five years — that's not an invasion, it's an occupation, and games writing is better for it.
I disagree. She presents herself as an outsider, like a scientist who observes the subjects of their study. And really, all of the articles she's written lambasting "gamers" would lead anyone to think that she doesn't particularly enjoy this hobby or even writing about it. Fair enough I say; everyone has to get paid, but let's not pretend that she's one of the gang considering she despises the people who participate in this hobby.
That's not true. She's very clearly legitimately in to games. Besides, what is this "gang" you speak of? This 'us and them, with us or against us' mentality isn't healthy.
