This is my Masilia game save. I have managed to create a nice distribution system in my city; food is not a problem. Prosperity isn't, either, even though you will clearly see my two slums. Other than that, the majority of the people are in large/grand Insulae. My palace block only has Large Palaces, but they are very stable and have lots of extra food. I am not short of workers, either. I think my city shows an efficiant distribution system in action.
