ok this will get of more fleshed out over time but for now i have an idea:
1. the world is created, with different biomes, resources and elevations.
2. people make settlements on it.
3. those settlements grow depending on their biome (openness), nearby resources (their usefulness depends on the era)
4. people make resources (farms) to help grow their villages, making resources is harder in regions of closed terrain such as rainforest or taiga.
5. each 12 hours, with increasing length per era, is 1 year in the thread.
6. if bong posts the thread is locked until his post is gone
