[Suggestion] Diplomatic marriages
Trading your children for world domination!
Once diplomacy is put into the game, it might be fun to be able to arrange diplomatic marriages, both for the sovereign, and his or her children. I don't think I've seen a strategy game deal with political marriages before, but it was a chief form of diplomacy between nations or vassals and lords for, well, as long as there's been royalty. Such a system could also feed very nicely into making moral decisions and tradeoffs, if there's going to be a morality alignment like there was in Galciv 2. What do you do if your kid doesn't want to marry a politically convenient ally.
This is just the very beginning of an idea, and I'm not sure how exactly I'd design it, but I'd love to hear others' thoughts about whether you'd find it interesting and how it would work. Would you lose control of the child character if you married them off? Would it a marriage be a one-time diplomacy bonus, or would it work over time? Should there be the risk of bad marriages that hurt diplomatic relations? What if the child character is killed?
Do the Fallen practice polygamy? If so, what does that do to marriage alliances?
Should you be able to marry another sovereign? Would the kingdoms have to combine or stay separate? Could it work like the senate in Civilization, where sometimes your spouse vetoes your desire to go to war? How would that work in multiplayer? Who would get the kids as playable characters?
