Incredible resource book, well worth the money. I've never found anyone who does such a good job of providing relevant, insightful and deep detail as Mr. Amthor, and he doesn't disappoint here. Truthfully, it's almost a jaw-dropping amount of detail on the city(s) inhabitants, factions, culture, institutions, etc. For example, the government section gives us multiple (10?) pages of details about the the Sel-Kai government, taxes, important city functions, justice (i.e.. who delivers it and how, severity of crimes, penalties), important city families, etc.... Add in a multitude of pages that describe various city structures, weather, herbology, languages, secret organizations, etc.... and it's easy to be overcome.
I hesitated to buy it as it didn't have RMU's changes in it, but frankly I'm tired of waiting for RMU, and don't regret that decision one bit. Yea the conversions will be a pain, but my overall satisfaction and general utilty of this resource will more than make up for it.
