This is a non issue for me.
NPCs that serve as enemies to be killed need to be politically correct or to adhere to any form of social justice agenda.
Yes I am a man and I really have no issue with the fact that men are overwhelmingly used as generic enemies in video games. For the simple reason that video games, like movies, are a form of entertainment. This sort of stuff doesn't matter.
It doesn't and shouldn't matter to people capable of distinguishing reality from fiction
A person who is capable of playing a game like Dragon Age should be sufficiently matured in terms of mentality to understand that this does not mean that video game developers are undermining women by not using them as enemies or are engaged in a massive man-hating agenda since they use primarily men. It is just a way to save resource expenditures and having sexually representative generic enemies does not exactly make a RPG better.
Video games are an interactive entertainment where every NPC is there to fulfill a role. The role of a generic enemy is to be an XP giver and to challenge the player, not to give some story depth or character depth of any form.
It gets even more interesting when we look at RPG games and see what is important and what makes them good. Good story, good combat, good followers and list of exciting places and dungeons to visit.
Having a gender representative generic enemy is not on that list. I do not recall any game that have become better by doing it. It is a waste of resources.
