it pisses you off that dead peoples eyes are closed...erm ..why?what do you want them to be doing.ive seen a few dead people throughout my life,nothing sinister just old dead people,anyway there eyes were closed man,thats what happens when you die.
Um, those few old dead people you've seen at funerals, had their eyes closed by morticians, regardless of what state they may have been in when they kicked. Wouldn't do to have uncle Wilbur's blank eyes staring back at everyone who came to pay their respects, now would it? Talk about the willies. From a purely realistic standpoint, the OP is correct- people, or any creature, who dies while awake will usually have thier eyes open afterwards. When you expire with a greatsword stuck through yer gizzard, you don't yawn, close your eyes and gently go to sleep... it's pretty violent and quick, and the eyes will still be wide open and staring up at the sky, as if wondering what the hell just happened. That's why in so many of the old movies, you'll see the hero closing the eyelids of their fallen comrades, after a battle. That was accurate.
But, I don't care if they put that little detail into a game or not, and I'm sure gaming devs are being a tidge sensitive to their critics who say there's too much awful stuff being added into modern games. And the little extras like open eyes, gaping wounds, entrails hanging out, that sort of thing kinda tends to remind people a little too much that the activities they're participating in really are simulating horrible actions against the bodies of another (virtual) human being. Gotta keep it at least a little bit clean, to keep the worst of the censorious wolves at bay. Beheadings, I guess that's acceptable. As long as the eyes are closed....
