I ordered The Great City hardback from Lulu. I've never ordered from them before so it will be interesting to see the production quality of a print-on-demand book.
The only issue I might have with this product is the map. For a city with 50,000 residents, it looks like it has too few buildings.
I think the map in the '89 City of Greyhawk boxed set experienced the same problem. And, later, when they re-issued a map of the city in the Living Greyhawk Journal they added more buildings to it.
In fact, I was doing some investigation on the 0one forums, and one of the designers posted this errata:
Great City Errata as of 12/20/09
Great City Population
Azindralea 8,000
Outer Boroughs 16,000
Total Population = 24,000
Apparently, this makes it a Large Town.
Anyway, I guess the map can just be representational and each building can really represent a cluster of 50 or so smaller structures?
