I've always found this the silliest possible complaint. It's like picking up a Die Hard game and being annoyed you're Bruce Willis.
I remember when Final Fantasy XIII was first announced and people were angry about having to play a female character. They were largely mocked. As they should have been. I'll never understand why the opposite complaint, not wanting to play a male character, is somehow credible.
It's silly to you because you are probably a guy. I'm a woman who's had to play countless male PCs before finally having the pleasure of making my own customisable female PC in Dragon Age.
Now that gaming companies realized protagonists don't always have to be men, they can easily adapt any story to fit for both male and female PCs.
I don't care how wonderful Witcher is. I want a story that respects my choice for playing as a female. Why? For two reasons.
1- Because at least half the gamers in the world are women nowadays. And I don't want to play as Standard_Male_Protagonist again.
2- Because male and female viewpoints are radically different. You can't derive any satisfaction from the Miranda romance as a hetero female, for example. Or from having to hear other male characters make sexist jokes about an NPC and see your male PC laughing at them while you're internally cringing.
It's simple as that.
