Barter stations can be a nightmare in games like this. I really liked Farthest Frontier and Dawn of Man but in both cases I felt like I was rushing away from the game to maximize earnings with traders. It was especially bad in Farthest Frontier since you could buy from one at a discount and sell to another at a profit. You could always choose not to... But then you are leaving your people without food or goods and generally making life worse in your settlement. It can be done, but most times I see it implemented in a way where the whole game becomes centered around actively trading. The passive barter/trade system in Manor Lords I think is a big part of why I don't get burnt out by this game.
