I have always had a very concise opinion on sexy girls in videogames but I am generally too lazy to explain it in detail. I won't do that ('Cause I'm a sloth) but I will at least try to summarise it here. Sexy girls DO have a place in the industry. whether it is on super stylized games like street fighter where everyone seems like roman gods made real or on JRPG's where everyone is a moving anime concept art. They are also not a problem stupid "Good and evil, white dude saves the world because he has inner demons but a heart of gold and so he does it because he must" games made to appeal to the biggest demographic in the world, they have a place and can even be fun in that. Hell, a sexy girl can always have a place on ANYTHING. The fact that she is smoking hot will not detract from the quality of the game itself.
The problem lies on the fact that EVERY SINGLE WOMAN on every single game has to be a woman that, on the real world, would be on the cover of every fashion magazine on earth. That alone diminishes possible designs for women, making every woman not only attractive, but just plain beautiful. Then you have to go alone and diminish that range even more. Why? Because we have to appeal to the biggest demographic we can. Our girl has to be A) White B) With hair at least on the neck and C) Have the measurements of bloody Aphrodite. This basically destroys any hope for variety in designs in gaming, making every single character have to fit into these set in stone qualities.
This lack of variety hurts people on both sides of the issue (or people who support a balance like me). The way it affects people who don't want sexy women in games is obvious, but I think that their opposite-minded folks fail to notice how this affects them: It deprives them from more hot women. Even if for you the type of woman mentioned above is "the perfect woman" there is still attractiveness to be found on, say, black women, asian women, latino(latina?) women etc. Not even going into the range of different ethnicities; A woman CAN be attractive without having proportions that guarantee that she won't be able to buy lingerie at any normal store. I want to write more, but as said I'm lazy so I'll leave it at that.
