i know suggestions are kind of out and they are just polishing the game right now but still,
i was thinking of an option where there is a ruined castle randomly generated somewhere on the map. (not on an edge of the world) doesn't have to be randomly but that gives u a bit harder time because it means you have to keep finding it if you want to use it. when you find the castle and you go to it you get an option to make a perm camp there (for idk what? 3000 denars?) youre men don`t get attacked there but when you are in it and an enemy is close they can attack YOU if they want. (like a refuge in viking conquest). but when you set up camp you get the choice to start repairing the ruined castle/fort.
it will cost you an amount of money, 50 men there at all times for building etc (can be a farmer or a swadian knight nobody cares). they will start rebuilding while you go through being a bandit or a noble traveler (lol no nobody does that). there will be stages like: first stage: they build half walls walls but no towers stairs or anything so its still kinda useless. second stage: walls are almost done they are starting on towers. third stage: they build towers and wall but no gate just a hole and they are starting on a keep and quarters for the men. fourth stage: keep is done and they are making farms for farmers and starting on the gatehouse. fifth stage: they made the gatehouse and the farms the castle is now done. its a way to create a kingdom with out making enemies at first it will cost a good amount of money and maybe items (and man power). this is just a suggestion but would be cool if i see this in a mod for banner lord,
