This is game/simulator that procedurally generates earth-like planets and populates them with a small pocket of humans which then spread and accumulate knowledge, adapting to survive on different environments and forming political entities such as tribes. The game even generates unique languages to name each tribe and their leaders. 

You can assume indirect control of the political entities once they appear, though this is a part of the game that is still not fleshed out. I have plans to eventually add technological advancements and complex interactions between groups of humans like trade, war and diplomacy.
