I think it\'s a good idea. Maybe the punishment is a bit too severe (seeing as how many, many people want to PK), so maybe it could be something like, \"Oh, you killed X many people, we\'re fining you X amount of money.\" The fine would depend on the player\'s level, so if you killed a newbie, you\'d be fined more than if you killed someone one level under you.
But there would have to be a way to determine if you PKed, or if you were defending yourself.
