Why does /v/ get so angry at "strong women" in video games? Vidya characters aren't restricted by realistic biological standards, and having powerful grills be playable adds some variety and offers some nice eye candy.
Of course, there are instances where the idea is executed poorly, such as in HZD, where the protagonist is a total cunt who's "toughness" seems shoehorned as hell, but there's nothing wrong with the concept.
