All my life, video games have attempted to cater, mostly to me, solely based upon generalizations regarding my gender. And they haven't been too far off. But if I were female, I would want a female avatar. I'd likely be sick of pretending to be a cigar-smoking space marine whenever I wanted to shoot somebody. This is where I'm coming from.
I firmly agree. In a game with character creation, I do feel somewhat passed over as a gamer when a developer makes a choice to not include women. It's not a matter of special treatment, it's that it shouldn't be viewed as special treatment at all. Girls are a big part of the gamer crowd.
To be fair, there's something to be said for getting to be a big stompy fat space marine and decorating my boots with some alien's intestines regardless of gender.
