The beautiful hardback city sourcebook Freeport: The City of Adventure blew the lid off the most larcenous city in fantasy. In this book game industry veterans Matt Forbeck and Hal Mangold join Freeport creator Chris Pramas for an in-depth look at the people, places, and politics of the city of adventure. Jam packed with info on the city, the Serpent's Teeth, and the sea lanes, Freeport: The City of Adventure provides action-packed material for any campaign. The book also includes a full color poster map of the city, beautifully rendered with street-level detail. Freeport: The City of Adventure is a must-have city sourcebook!
I have been heavily editing this for my campaign world's version of Freeport, and while I don't love all of it, it has a LOT of fun "meat" on its bones. The designers certainly know what a DM needs to run a fun game, and they supply a lot of it here. Some is too gonzo, some is too grim and dark, but a LOT is very useful to me.
