I don\'t know if this could work, or even if it would be worth doing, but it might have some nice uses:
To perhaps have NPCs fully controllable by game moderators and developers i.e. they could choose to inhabit the body of a NPC and role play as this character - this may be useful for special events, it also may help in moderating the game - the perfect place to observe from. This would also create an element of unpredictability to the game and allow the staff to have some fun at players expense as well
I suppose the controllable NPCs would have to hold no vital information or be part of a quest i.e. you wouldn\'t want this feature to get in the way of a player trying to complete a task or quest.
I started thinking about this after reading the topic about having a tavern for the demo. Hopefully many people would go here to meet and chat etc, especially at the beginning. You could make the host/hostess of the tavern a real person - and when that person is not there the NPC would resume it\'s normal behavior. I would love the chance to spend time welcoming people to the tavern and playing hostess
