In this city I managed to get Culture rating of 100, prosperity of 100 and Kingdom of 100 in a city with 14,000 people. This level is difficult because there is barely any water and the land is extremely arid. I mucked around on this level for about 120 years destroying it all the time and starting again. This city is pretty cool on the circumstances. It takes careful city planing because there is barely any water.
This custom level is available at www.pharoah1.com and is not in the original game.
