While every settlement you build in the popular new medieval city-builder Manor Lords will need to keep itself afloat with basic necessities like timber, firewood, and something decent for all those hard-working serfs of yours to eat, the resources in each region largely dictate what you can and can't industrialize as you progress deeper into a playthrough. You likely won't be able to smith lots of armor and weapons if you're not in an area with a rich iron deposit, for example, or your meat and leather surplus may be paltry due to a lack of nearby animal habitats.
Lots of the Development upgrades you get access to by growing your population and upgrading structures make it easier to play to your strengths with new technologies and refineries, but there are two extremely powerful ones in particular that supercharge trade, a very important part of Manor Lords' mid-to-late game. Trade enables profiting off of extra resources and materiel you don't need for the continued development of your city, while simultaneously allowing you to supply your people with things they can't grow or make themselves.
