This city is so vividly described that it seems like a real place. It's like the old Volo's guides on a much bigger scale.
LIKED: The scope and detail of the city are amazing. It's not hard to port it to another setting - surprisely the hardest part is a game mechanic where characters have multiple lives. The background of the larger empire is farly easy to work around.
DISLIKED: It's difficult to piece together an overall map of this city - it's hard to put the sections together until you've studied it. This is pretty important in a city book.
