I suspect each city is going to be somewhat different, simply because of the individual ways each of the city must accommodate their membership, cultures, geography, etc.

For example Babylon will start either with a major city in a specific Empire, or I could be persuaded to start with the Empire, then drill down to the city.

The depth to which folks choose to "drill" in large part will determine what graphics they need. Here's my bare bones, no nonsense take on it:

1. Neighborhood emblems that will automatically position beneath the members membership emblem on their home page. For example, Citizen of Nineveh, Citizen of Memphis... whatever

2. Homes of various types: Villas, homes, inns, reed huts, etc. We'd have to supply you with some kind of example for the different areas.

3. Kinds of transportation: Chariots, wagons, "carriages", litters

4. Perhaps public buildings? Inns, souks, fishmongers, weavers, temples, palaces?

It's hard to envision anything more than that right now, because we don't have more than a barebones idea of what else we might be able to do.

It could be that some nice uniform decals or buttons might be used on neighborhood pages... and it could also be that the number and complexity of estates one can purchase might escalate when the cash boxes are brought online.

Hope this helps! *S*
