"I've been noticing that when you hit someone with a sneak attack, specifically a sneak power attack, both the player character and his or her victim will emit a vocal noise of some sort. Wouldn't any nearby enemies hear the sounds and turn around? All I'm asking is for Bethesda to patch the game so that when you sneak attack somebody, neither character would make any vocal noises. This would provide a more realistic experience."
Translation.
Anyways, I think the real issue is enemies talking during an assassination. I once had
say "I haven't even gotten started yet" when my character had his sword impaled through her sternum. It was pretty silly.
