Well, if you have farms (included in small villages, as would be small mining camps and trading posts, I would think), you will need livestock and pack animal models and art, carts, farming tools, farmer's garb, huts and fencing (perhaps dynamic), new map textures, skills that support farming (perhaps even smoking meats in time!), a system of farming, perhaps fishing, stories for each farmer, miner, or trader, and some quests to match.
Plenty to do there.
