What makes a person a gamer anyway? Do I have to wear a "geeky" t-shirt that shows I play videogames? Do I have to like Halo? Am I allowed to say I'm not a fan of the Souls games, or is that an automatic ban from the gamer culture? Can I play games on the easiest difficulty and not be called a "casual" because omg, what a tragedy, I suck at videogames?
Also cultures change over time, so if there is such a thing as "gaming culture", you don't get to say "but you're not a part of it unless you can do this and this in that and that game, casual noob fake gamer girl!" if that's what you mean by "gamers" controlling "gamer culture", because things aren't the way they were years ago, there's a lot more people now and they probably want games that cater to them too. If half naked girls are getting new clothes in games now, that's just another thing that's changing, maybe they'll come back in 10 years or so wearing even skimpier outfits, who knows.
