I'm looking forward to your next update then, and I'll try to spot those U's you've missed

As far as the City State/Kingdom discussion goes, a City State refers to a very small nation - no matter the style of government. Rome started out as a City State; at first it had kings, but changed to republic later on. That form of government persisted until ca 30 BCE, but Rome had stopped being a mere City State long before that and was in effect an empire even before the ascension of Augustus. The same thing can be said for the old Mesopotamian City States; they were ruled by (priest-?) kings, and that didn't really change when some of them expanded beyond their original boarders. You can of course keep the name City State Union, I'm just offering a different take on the whole thing =) I like the concept of it, and have been toying with something similar myself. What you can do, is keep the name as a memory from when the cities rebelled together, but everyone living in the nations usually call them for "kingdoms" or "republics" or whatever government form they may have, or simply refer to it as "the Union"
