Just thought it would be cool if you could (in addition to your sovereigns actually name), define his or her title as well. What I have in mind is sort of like in the Civilization games, where you can define a range of text strings the game uses to describe your leader and your civilization. For instance, you define your leaders name, your civilizations name, as well as the prefix applied to things belonging to that civilization.

It would add alot of fluff to the user created kingdoms and empires if you could make your rules the "golden emperor", "warchief" or "duke".
