I relooked at the information, it made me think- If they did happen to make the AI so advanced where they would go to the nearest town to buy something like crops if all of theirs were burned down, it could introduce some interesting mechanics. There could be a Caravan system, perhaps you would be able to ambush a caravan enroute to a town; maybe there could be jobs such as defending one. (Pictures Jurassic Park T-Rex chase, except your on a donkey caravan hauling ass being chased by a dragon.) Chances are it's just going to be prices increase in the town, and supply in another town decreases. Hopefully that isn't the case however.
