An economy would be great for sure, always wondered where do the villages get the money to buy off all my loot when they themselves have nothing to offer nor start any caravan anywhere. They shouldn’t be able to buy off my stuff endlessly while being raided by bandits orcs undead. And if they wouldn’t able to buy off all the loot, the play would have a reason to try and defend or do caravans at all. Now as it is, there is just no point in defending the settlements.
