4. it don' matter that vanilla already has some factions, if your gona make this mod, you MUST make new units and skins for vanilla
5. this mod doesnt require much work, you could just wait for all the major mods that do the "big nations in history" like take zulus from the zulu mod, trojans from troy, greeks from some greek mod out there, romans from some roman mod out there, mongols from khan, japanese from sengoku jidai, and HEY! you forgot native americans!
