However your world is run, there are bound to be malcontents (as there are with any system) so how do your authorities handle this? Is there a press/media base? Is it freely run or is it controlled by the goverment and whichever way you answer that, can you have things go wrong by someone seeking to impose control or by coming out with something they know the authorities won't approve of?
What is the source of energy in your worlds? How is that controlled? Do you get criminal activity and, if so, how is that handled/punished?
What happens when the entire world is threatened? Who is capable of doing that and why would they want to do so?
