Sooooo I suppose this isn't EXACTLY relevant but I did kinda want to brag and since we're on the topic of girl gamers....... So my girlfriend can kick my ass at any iPhone game that exists, like Tiny Wings, Super Crate Box, Temple Run, whatever. But she never bought a console and didn't have a computer that could play games effectively. One day I bring my ps3 over to her house, I tell her that we're gonna play Borderlands 2 instead of watching Dawn Of the Dead (again, ugh). She is not initially excited. Cut to three hours later and I'm the one who wants to stop while she's dead set on completing the next quest. I created a monster. Last time I brought my ps3 over to continue our borderlands game (playthrough 2 by now) she asked if I'd brought Bioshock Infinite, which she'd read about and knew I'd gotten (because everyone knew because I shouted it from the top of a mountain). Anyway, I hadn't, she was miffed, and I was ecstatic. She's a big fan of the bucking bronco+ charge combo nowadays. Now the reason I was so happy is not because I'd just created the nerdy sex goddess that my thirteen year old self always wanted (although I totally had, bonus) but because we had discovered another shared interest. Before when I wanted some game time she would always sit next to me and read a book, occasionally glancing up when I'd point out some visually stunning piece of digital artistry. But there was no real engagement. Now we're experiencing the same things, talking about them, problem solving together, and it's absolutely wonderful. Go gaming couples!
On the gender issue side of things, I see two problems that stand in the way of equal status for girl gamers, and one of them is pretty much insurmountable unfortunately.
The first is that your average male gamer is used to having things marketed to him. Look at typical video game protagonists and you find the expected plethora of square jawed manly men doing manly things. Booth babes (hate that phrase, haven't found a better one yet though) are the logical extreme of this. Now, because developers (usually at the behest of their publishers and producers) use sex to sell video games, your average gaming male expects that. He sees an attractive woman seemingly interested in video games and expects a trick, a sales pitch, or a lack of actual enthusiasm on her part. "What, Jessica Nigri dressed up as Juliet Starling!? She must be getting a huge paycheck for that! It couldn't be that she's just looking forward to the game!" If I got a chance to be the official cosplay face of saaaay- Booker Dewitt, I'd pounce on that shit! Luckily I think that this attitude will pass as gaming matures as a medium and diversity continues to improve (both in the industry and player base). Unfortunately, I think the second problem is a much larger one, maybe too large. And that's the entire way the English language is built. Bear with me here, think of all the gendered insults we have. There are so many that its what we go to first. Likewise, when some angry asshole who just got his head blown off in CoD three times in a row by xxXFemmeFatale420Xxx. What does he do? He goes right to the insults based on her sexuality, attractiveness, or dependence (on a man, I would guess). It's a societal problem and won't change without serious strides in the feminist movement (yay!) or a complete overhaul of our language.
And if you're one of those people, guy or gal, who thinks that there is some unspoken "requirement" in order to be a fan of something? Shut the fuck up, who do you think you are? Some kind of bullshit cultural gatekeeper, trying to keep things "pure" for only the "real" fans? Try to be inclusive, it's how good communities of fans form.
Sorry for the long post, didn't mean to type all that but it kinda came pouring out. Hope you stuck with it til the end and I'd love to hear some replies.
Edit: I fucking love Kingdom Hearts, the second one in particular, that game got me through some seriously dark shit. Some people above mentioned it and I just kinda wanted to throw out some KH love.
