But the interesting part is that these activities would by nessecity require a unit type that could only be defined as workers, which would in turn create essentially citizens with possibly a mayor acting in the role of warlord. I guess what interests me about this situation is that it represents(at least to me) the most radical potential change in the story line.
I wonder if there is a basic unit that can be popped by cities. However, nobody every pops them as they are "useless". If you pop one, you have to immediately pay to upgrade the unit so that it can fight.
Also, I wonder how unit pop selection is handled. Is it a menu, or does the Ruler have to know that the unit type exists.
