Yeah, it's not the most heinous examples of sexism, but by definition it's there. Guess what? Until it goes away, people aren't going to stop talking about it.
Producers, some, but not all, are making decisions that hamper the appearance, and/or agency of female protagonists.
Developers, some, but not all, are making decisions to show women in positions where they have no power really often, making jokes like "Bros before Hoes" (Replaced God of War trophy), cutting women from games, and a plethora of things they weren't perssured to do by the Producers.
Videogame market testers, some, but not all, that don't consider girls into their test groups? Wunner why. Stereotypes that they don't play games?
Some but not all of the gaming community?

Fish in a barrel.
Sexism exists. Women are being treated worse than men on pretty much every level of gaming.
I have a general loathing for the gaming industry for this crap. I recognize that it's not the entire industry but until I know who to blame, there's plenty of loathing to go around. Few companies are exempt because they're generally not hung up on "It's gotta be a guy, or it won't sell" or "She can't have a relationship" or other BS like that.
Now, to be honest, I don't have a huge problem with women looking sexy in a game. I have a problem with who they are, and what they're doing while looking sexy more than anything. (Scratch that, they don't even have to be sexy for those problems to arise) If it's really close to shallow, and nothing, or practically non-existant personality, and nothing? Yeah, I'm gunna get annoyed with that character. How much depends on how severe their treatment is.
I can see how oversexualization can harm perceptions of the industry, though. When a busty, jiggly woman is wearing 3 doritos worth of cloth tethered to her by string and she's not going swimming? Come on.
I don't have a problem with Samus (Cept Other M's version),any version of Lara Croft, Bayonetta, Nilin, Jade, Jill Valentine, Claire Redfield, Mai Shiranui, Cammy, Mileena, Ivy valentine, or pretty much any woman in Metal Gear for the most part.
Hell, best way to have me like a female character is to make her playable, and capable from one end of the game to the other, or give her a reason for being there besides being a plot device. Then it becomes a question of how good the game is.
I'm not particularly opposed to violence against women, I'm bothered, however, by how often it's perpetrated against them vs them perpetrating it. There's a crappy balance there.
Maybe if there was a well balanced amount and variety of women in videogames, topics like these wouldn't arise so much? Women wouldn't be lightning rods of controvercy if their depictions were more frikking diverse, and common. People who talk about women in games would have more to talk about, and more diverse opinions.
While I'm on it, what grinds my gears are the people that only complain about how guys get shafted in games when people are complaining about women being treated unfairly. It's like they save it as ammo to make people shut up more than really caring about it.
