Ah, you give us humans such little credit. Wouldn't it just be a little fun to turn off the NPCs and give the players some control, at some point, someday. This is way down the road of course because the game would have to be pretty much finished with the ability to build, uphold/enforce laws, create their own markets, etc., but it would also be fun to test it out in the current stage, just to see what would happen. It would be chaos and things would get out of control, but after the 10th or 11th try, people may learn how to do it right. But, I have confidence that us humans would find a balance and it could make for a pretty incredible game.
This may be for a wishlist item, but felt I should explain the above and how I envision it would allow for an incredible roleplaying experience. Yliakum would be a disposable world. You may still be able to come back from Death, but the world itself was destroyable and had limited resources and space. For example, in the beginning, one Yliakum is built from the ground up. And I mean ground up, no cities, no buildings, just like the RTS strategy games, from scratch. As the real community builds cities, establishes governments, trade routes, economies, I can imagine total chaos, anarchy, rebellions, booms and busts, and if Yliakum doesn't make it, if it gets destroyed by the roleplayers, then so be it, the world is destroyed and another instance of Yliakum is started from scratch and off everyone goes again. The players would have to have some serious control on the game though, hardly any restrictions except for the laws of Yliakum, gravity, environment, available resources, etc. I'm curious to see what kind of roleplaying occurs in a place like that, alas, if I was only a programming genius, oh, and had a couple supercomputers lying around...
But giving players the control to have a "position" in the game, does not give them automatic power, they can and would be overthrown if they were not being fair to their role. As long as the game allowed for others to uprise and have an opposite and equal effect in the game.
