The only requirements are that it fits on the map and doesn't have whacked out technology (no guns or death stars).
The year will start at 1,000 BC, after the fall of Mycenae, when the Dorians and Ionians are first starting to start cities.
Already made factions are below:
Sparta (NPC, will run a greek alliance thing)-Me, as ruler of the NPC
Etruscan Cities-Frederich Barbarossa
Sparta-Me, as master-of-NPC
The rules of faction creation are essentially nil, besides, as above, be logical for 1,000 BC. Heck, you can be Irish, Chinese, Greek, Mayan, I DON'T CARE! I just ask that you are logical for the time period.
This is a huge WIP, I just want to know if anyone would care for this.
