Tarnicus: After studying politics and economics at university, and then having life show me the non-human side of things where our laws, beliefs and actions are a minute thread of a larger complex organism, I think I'd get the shits playing a game that is so human-centric :P
Yes indeed. As someone who has studied the principles of emergence, chaos dynamics, and evolute heuristics, I'm of the mind that you can only truly simulate something by creating a complete simulacra. Specifically, to properly model part of the universe, you first must model the universe.
I expect the game is still fun though, and hopefully contains some good governmental and civics lessons. I think it helps to ease people into complex subjects by exposing them to even those fundamental parts they may not yet grasp.
