The one thing that never changes in all these TES games, is the npcs always talks [or complains] to the PC as they pass by [I suspect the reason for players wanting to kill the kids]. We don't like it in a game, we don't like it in life [Of-coarse the developers will do it again in the next TES as if they actually paid attention to any player's recommendations]. Is there a mod that silence the npcs or reduces the dialogue distance?
