Manor Lords:
Ok, from a city-building/no combat perspective, you cannot expand your first town/area across-regions.
The way it works is if you claim another map region, it becomes like a new-start town. Plop down a starter tent w/5 families there, and go thru the entire process of building up population/town buildings again. Although you can make it less advanced/large, of course, if you just want some outpost-like resources. But if you want to use/gain resources from that region, you don't just give it to yourself freely - you must build tradeposts and barter goods with that region - send firewood for wheat for example. Ppl/carts have to travel back and forth. The exchange rate is not 1-1 either, dunno the maths, different for different resources. Which works, is more "realistic" too (other regions are like your surfdoms?), but it is a cumbersome exchange system (as is, it could change).
So that is a little deflating. Some of the regions are large enough to be fun to fill just "your" area as a playthru, some are much smaller. I suppose you could have a goal of getting every region stable (where you don't really have to manage it much anymore, which is totally doable) and just keep doing it in all regions, where the management would be the barter system to give some regions resources they lack - kind of like 8 maps in one save, ha.
It totally makes sense in terms of the light RTS/combat/defeat AI to claim regions, aspect, tho. In that case you wouldn't be focused on building so much as claiming regions before the AI gets them all/you.
I think many of those wishlisters are going to be disappointed that it's not either "Total War Killer" and not Banished/Ostriv. It's more like a combo of Banished and Stronghold. Maybe. I still like it tho. And I love restarting. We'll see what updates bring someday.
Edit: it's Stronghold feeling in town-sandbox, I don't mean SH's combat or castle defense.
