The idea is to get a large population into a medium sized map with a high prosperity. Desert map, no military activity, hard assignment.
Required ratings: Prosperity 100, there is only one wine so you need plenty of villas and the rest of your housing must be mainly large/grand insulae, wells and gatehouses are disabled. Culture 50, I do not like culture parks. Peace 10 Favour 80, there are frequent varied requests. Population 10,000
There is more than sufficient trade. Food, plenty of farmland and fishing.
