I can agree that running around town with weapons drawn (equipped) is unsightly. I have caught myself doing it more often than I care to admit as well. While we are on it, why are so many people wearing armor while in town?
But herein lies the rub. Let's say I am overweight and using a seduction weapon. am I to dequip it and be stuck or drop items before entering town or dealing with NPCs. As someone said earlier, simple requests usually have far reaches consequences we don't even consider.
Now if there was a way for NPC's to recognize the use of a seduction weapon and ignore it being equipped then I agree, implement a no NPC with weapon equipped setting.
The point of this game, as far as I see it, is fun + realism. Seduction weapons can be argued as to realism, but why couldn't I have an item (weapon) that magically increases my strength? If I am required to hold it in my hand then I should not be penalized for using it.
