I have been thinking if the game later on does not have boarders that stop over expansion with out challenge(not count hoards and stuff like that).What I mean is you start wth a chunk of land(like normal) and near you is a flag this flag gives you control of the region.
Be side your region is more regions some will have NPC villages and others will have evil forts of ruined villages with undead(or peaceful land but who cares about that)
So you will have to trade with other npc(or players if possible)
This will give a very game of the thrones feel.
I’m no programmer just very creative if you can make this a mod PLS DO!!!
ignore my grammar…
