Really, people crying sexism every time they see attractive, scantily clad women in a game, book, movie or whatever, need to have their platform yanked. The problem is that the media keeps giving a platform to garbage like this, so whenever someone wants 15 minutes of fame they jump on it and make a stink.
As I've been saying for decades now, what men and women find attractive and appealing overlaps heavily. You ARE dealing with idealized physical images and that is universal for both genders, just as the way men are portrayed in fantasy as having crazy amounts of muscle definition and so on.
It's sort of like someone looking at a piece of fantasy artwork, insulting it as sexist and demeaning to women, and then finding out it's by Julie Bell or another female fantasy artist. A total joke. This is just the video game version, I believe similar things have happened with some of the Anime/Manga produced by Clamp over the years as well.
The biggest issue I have with this article is that there is an article... assuming it's a real issue, as opposed to some offhanded promotion, with the developer itself claiming the contreversy to get attention, I had never heard of "Skullgirls" before this for example. In such a case I think it lacks class, but I suppose The Escapist has to pay it's bills and it's no worse than running any other advertising.
