It would be possible to create a simulation environment in which randomized individual characteristics (both in the artificial entities and in the players) combined with a randomly generated, organically functional, resource rich world, especially if you included needs-based AI and trade based on basic economic presuppositions. I’m considering attempting to design such an experiment, just to demonstrate the efficacy of free market principles. Multiplayer would be a must, of course. Emphasis on realism as opposed to environments conducive to dogma would also be a must.
