Ya, the map is 84 tiles wide and 52 tiles tall on normal Big and Small. A hefty 1250 land tiles usually. It would take huge guts to go for a religion against 5 Deity AI, hoping one them does not start with Mysticism. Almost has to be Agriculture -> Animal Husbandry unless someone is comfortable growing with a Granary, unimproved corn, and unimproved pig. But then how does one make a Settler with no improved tiles? Without aggressive AI, Worker stealing is a questionable risk with only 5 AI to trade with, Deity AI that won't ceasefire, and Izzy being able to make them easier. But the capital does have a Castle.
