We have dragons, golfers from hell, sumo wrestlers, cartoon characters and everything else. Lots of quests and mini-quests which require a mix of fighting and problem solving. Player killing is illegal though we are moving control of this from the arches to a council of elected Avatars who will oversee player law. We respect individual policy as much as possible. Wizards cannot snoop a player except in areas they have created, and only for debugging purposes, not if the player is talking to anyone else.
Arches only snoop for debugging or game security purposes.
We have numerous private and snoop proof rooms available. Of course, if you don't make it obvious that you have multiple characters, we'll never know. Wizards allowed to talk to players, etc but not share quest solutions or help in combat. Major changes or additions by creator must be approved, like adding a guild or club to an existing area. Wizards can work individually or as part of a domain.
