Honestly, them managing my towns isnt really the feature I was hoping for, because personally I like to manage my towns myself, and well AI's tend to mess it up.
For me, the idea of having a npc leader arise or be assigned who applies bonuses to the town/region, that I can choose to move based on my needs and desires for my towns is what I'm looking for.
If a town is well outfitted for research, I'd like to set a governor who'll "run" the town to peak efficiency when it comes to research. If I have a town at the front lines, guarding an important mountain pass, I'd like a military oriented leader there to run it. They dont necessarily have to literally manage my town, but since ai driven governors are generally included to micromanage towns, I figured, why not give them some personality and bonuses, and let the player decide if he wants to micro manage or not.
Worst case scenario, at least give me civic heroes, who apply town or region wide bonuses/penalties based on what he's good at, whether that be research, military, economy, etc.
