I really like reus, a god game you can get off steam. I thought a reus mod would be cool. It would add new villagers. Nomads: wonder the earth until they can find a place to settle, Desert, Forest, swamp, tundra, and mountain. Each type of village will develop different things based on environment. You help them build structures and can figure out what they need to build it. When you build one new types of villagers will appear and you can reap the benefits! Villagers will also go to war if they get greedy. You can check all this with a village management block or something.
Someone make this for forge! P.S. this might be a big mod.
