This city was built in Very Hard difficulty, without charging any taxes, and without building any patrician houses. It is nothing but Grand Insulae. Only 15 oil per year could be imported until late in the final year, and in most years only 12, since just one ship from Lutetia could be on the map at a time and the dock is a very long way from the entrance point. For this reason, it is unlikely this city would remain stable for too long without moving the dock.
