People like what they like. And an awful lot of men on the planet enjoy scantily clad, skinny women in their video games. And there are game developers who will give them that (and possibly enjoy it themselves). Hell, I'm bisexual so even I can appreciate it to some extent, even if I don't seek it out.
So attempting to change what people put into their games rather than ignoring them and buying the games you enjoy (that don't include these women) doesn't make very much sense to me.
They're not real people. They don't care if you objectify them. Why do you?
