I'll tell you, if you want find some men who like to play women, just go play Guild Wars 2. I swear like 4/5 female characters are played by guys.
I've decided it's because most of the female chars are only half dressed. HOWEVER.
This is the character I run with. Or at least, this is a picture of her armor. Which I pretty much love. (Though mine has much better colors.)

Now. What do you make of this page? It's a fansite, which has pictures of pretty much every piece of armor and every weapon and every color and every hairstyle etc in the game. But skimpy armor has it's own special page.

Shock! Horror! But guess what? Dulfy is a girl.
I don't honestly mean to keep going to armor, considering my last point and the rebuttal- this was just a natural progression of why I think guys roll females in GW2. Or at least, why they might roll females.
Some women love that style of "armor" -- I can't really justify it by actually calling it armor. I'm sorry, I just can't. It's purely decorative and while sometimes it can look kind of cool, it's not protective at all.
And I can see the appeal of some of the less revealing versions. Some of it can be cute, it all obviously looks sexy. But there are settings where it fits and settings where it doesn't, and a gritty "realistic" fantasy--or at least as realistic as fantasy can get--like Dragon Age, or Game of Thrones, isn't the right setting for that type of armor design. it works for settings with a goofier art style, or with a less serious setting. But it isn't meant for the women, even if there are women who love it. It's geared toward men and boys who want to see their female avatar shake her stuff.
Again, it has little to nothing to do with marketing, unless you're putting forward the notion that Bioware should market with scantily clad female characters, which may have the result of pushing away more female players than it would draw in. I am not sure about that--honestly I used to be totally okay with the skimpy styles until I ran across games where my female avatar could wear actual armor. In other words, I was okay with it because it was the only way I could play a female at all, and because the game industry was so inundated with women dressed like that that I didn't really pause to think about it or what it meant.
I'm sure there are people out there who still don't realize that they have a choice in how their character represents them, and again there are women who like skimpy armor--and that's perfectly fine; I don't judge anyone for that, though I do take offense that someone may think it's "because we want the women to be more like men." In my case, it's because I want my female heroes to be believable and because I want their appearance to garner more respect. That may seem counterintuitive, since in all honesty I wish we could wear whatever we like and still be respected. Unfortunately, that isn't the case--and it's especially so when you're playing a female avatar, especially in an MMO. At least, that's the case in my experience--you're going to be harassed, you're going to have guys say they wish they'd played your class/race because your avatar is sexy (which is sort of a compliment but can also be downright creepy depending on context), guys will try to give you crap for no reason, they'll try to wheedle you into cybersex, they'll mock you and say you're a guy or they'll mock you saying girls don't know how to play if you correct them... it's annoying.
I'm personally not one of the people who enjoy skimpy "armor," and even if the style does fit the setting (it would have worked better in DA2 than in Origins or from what I'm understanding Inquisition will be like), I don't feel inclined to play a game where my character's barely clothed but everyone around her is fully armored. If I join such a game, you can almost bet I'll be playing a male avatar, just to have clothing--and to not be harassed by male players who keep trying to give me stuff or telling me how sexy my avatar is in the hopes that I will offer cybersex. Yes, I have been harassed in that way, more than once. I did not enjoy it. It's one of the reasons I don't play MMOs, despite having tried several of them. But not everyone's experience is the same, and more power to anyone who doesn't have that problem or who does have it and doesn't care.
And that said, I still want to know what the armor talk has to do with marketing, unless, again, you're suggesting that skimpy clothing is a great marketing strategy. I disagree, because I personally don't enjoy being ogled and I would actually not buy Dragon Age: Inquisition if my only choice were to wear skimpy armor. I don't know how many women agree with me on that, but considering how some people I know react to the attire of certain female game characters, I suspect that there would be more female gamers if female characters in general tended to be dressed more modestly. I will also point out that while sex may sell, when you're telling a mature story it is going to be hard to take it seriously if half of the population is in their underwear. It will also make the story feel less mature if the players feel that the developers thought they had to sex up the game that much just to get them to play it--it's insulting to men to say that they're so controlled by their raging testosterone that they can't help but buy a game with nearly-naked women in it. Not that there can't be mature themed games with skimpy armor; I'm sure there are and have been. Again, the setting and art style matter.
