I have some players who would be interested in managing their own city. Is there any literature out there which covers the ins and outs of PCs governing a populace?
Some example scenarios:
The PCs raise taxes way too high in a fit of greed. The population turns to their torches and pitch forks.
Funding hasn't been getting to the medical quarter due to corruption.
A competing faction's army is gathering on the horizon. The PCs must call their men to arms and lead them to battle.
Tagged as DnD-3.5 as that's the version we're playing, but feel free to suggest literature from other versions and systems.
EDIT: Also of interest would be the economics of such settlements. GDP, trade, agriculture and the like.
