One of the things I've liked so far in Elemental has been the dynasty system. It's a neat feature that really humanizes the sovereign for me, and gives a sense of the passing of time. I remember playing games like Civilization, and being Genghis Khan or Napoleon, etc., for the entire game, some ageless god form of the historical figure. Watching characters be born, come of age, be placed in succession for the throne, etc., was a really nice touch. It got me to thinking about what others have thought about it, or how it might have affected their gameplay.
Here are some of mine:
I won't marry off my daughter to another kingdom cause all of the eligible bachelors have dumb sounding names 
I felt bad when my first son died on a quest, whereas I didn't feel as much if a nameless troop died.
If I get enough gold I'll take one of my kids on a shopping spree with the kingdom's treasury and give them all the best stuff from the item shops. The citizens may just have to skip a few meals while I make the money back 
I found myself having favorite kids and letting the other ones stay inside cities while the cooler ones got all the xp and loot hehe. That might be kind of mean but I'm playing an evil character anyway.
If I can't think of a name for a new city I'll name it after one of the kids.
