[@Run9] You need to know what Era your in in order to even start thinking about kingdoms and politics, otherwise you don't have any kind of knowledge as to the tech level, which affects communications, which affects maximum size and political alliances. 

[@Kenaron][@Run9][@rush99999] I don't mind working with a team, but Rush was here first, so after this post I will back off and see if he is willing.

So flora, Fauna, Magic(?), Races/species(?), Landmasses, land continuity (Pangaea, continents, islands, ect.), Environments, Divinity (if real, otherwise an aspect of the Kingdoms section), World size, World Age, and I believe I'm missing some pieces here, but this frames step one.

Era, Kingdoms, tech, politics, resources, history, legends, religions, knowledge, population spread/density ect. is step two.

Then the polish, refitting, and anti-contradiction measures.
