PKing and the Lack of Penalty associated with it.
So I've Farted around in this game and there is almost no reason not to run around just slaughtering everyone ... If a Red Dies there is almost no penalty to it. A lot of people will take an opportunist approach to killing someone. There is no real penalty to the act of Player Killing ? Sure if you go red you can't visit the "Blue" towns but they have their own towns that explicitly protect them. So this goes back to where is the penalty ? UO atleast had skill loss for ressing while red.
