After about 5 years I'm glad to be back trying this mod out that I'm loving it. I loved it in the past, and I'm loving it in the present that I'm also trying it out to see what Rising World could learn from it as well that it's just fun seeing NPCs build.
*Needs Forge to run
You basically wander around the world seeking a settlement to help out that any cobblestone you give them you'll see them build with. Anything you give them (those that they accept) you'll see them using. You'll see them expanding out making fountains, homes, blacksmiths, farms, among many other things that the higher the reputation the more they'll allow you to do. You may even gain yourself a house heh. It's a fun mod to play with that I can't wait for Rising World to reach the point where NPCs will be able to do similar things by gathering resources (Safely), even if it's in a "backdrop" manner of just dipping a staircase into the ground in a fake manner for NPCs to "fake" gain stone.
These settlements show what resources they need so you could take it upon yourself to go out into the world to gain wool, food, stone, among other necessities that you'll see these settlements evolve from mud huts to proud stone settlements, or more.
The images below show me helping out the 'Normans' that they're just living, building, and expanding with my influence.
(This is all science to predict how Rising World could probably play off of this.)
