There's nothing inherently wrong with male orientated games. If you're a fan of fighting games, Soul Calibur has more than just Ivy's tits going for them (Of course, what turned me away from the series as if it were the plague was watching my brother make loli after highschool girl in the character creation but I assume that most people don't have this problem.) The portrayal of women in these sort of games isn't that bad in itself, so I don't think that it requires that big of a fuss. Characters are characters and if designers want to make big breasted women in their games, that's up to them. In many games, there are other women to counteract these ones. For every Ivy, there is a Xianghua or Taki. Where you have Miranda, there's Tali, Ashley, ect ect ect.
Yea, of course there is room for improvement. This is a medium that is still being developed, like movies, books, and all sorts. Sometimes there are steps back, but there's nothing wrong with sexuality in gaming, no matter what some newsgroups or political parties might say. I will, however, keep my fingers crossed for posters that focus on male character's dongs or glistening muscles, just to see male gamer's reactions to them. Maybe it'll be on par with female reactions to Soul Calibur posters.
