Why on earth would the darkspawn remove his underwear? Taking the armour, yeah makes sense cause it's good and maybe even be seen as a trophy. Taking off a probably **** stained piece of cloth? Why? You say it doesn't make sense that it's on, I say it doesn't make sense why they should remove it.
Where did I mention darkspawn removing armour?
Games aren't real life, this whole realism, that everything needs to super gritty and depressing doesn't fly when we can shoot fireballs out of our hands. Showing ******, because in some deluded way of thinking that¨it's more mature, doesn't make it so.
Realism is not "setting." If Dragon Age was set in a "light-hearted fantasy" I'd be more than opposed to nudity and even gore. But its not! Dragon Age deals with terrorism, rape, sex, violence, theft, slavery, human-traffic, genocide, racism, religion, politics, war, rebellion, human-sacrafice, drug-trade, betrayal, murder, gang-crime...
I don't think people realise how serious these things actually are. But because Dragon Age has not been able to visually express these themes is some sort of pathetic fallacy, it goes by quite unnoticed. Furthermore, the entire romance and companion aspect of the game tends to get more attention (and for good reason, since they're done brilliantly.) Consequently, this also leads to the more serious issues of Dragon Age fly by the player who doesn't read in-between the lines.
