I just attempted a test-run to see if I could achieve the proper setting for the game. I conquered Spain before 800 AD D), made all my cities stop working all their tiles, and basically let the Byzzies go to town on my cities (playing DoC, by the way). But they took Mecca, and then I got "exiled" to the Vikings! So it didn't quite go the way I planned. I'll try it again with regular RFC. And see if I can manage it.
