For anyone that has stumbled upon this article ......
I pre-ordered this book from Green Ronin's website. It arrived probably about 3 weeks ago.
This is the BEST campaign city I have ever read!!! (and I own the original FR1 supplement Waterdeep and The North, the original 2nd Edition City of Splendors box set, 2nd Edition The Free City of Greyhawk box set, and the 3.5 Waterdeep: The City of Splendors book ..... Freeport tops them all!!)
I can't say enough good things about this book. It is top notch in every way. The attention to detail is tremendous!! GR literally tells you EVERYTHING that goes on, has gone on, or might go on in Freeport. This is the most complete city supplement I have ever read. It even has a sweet introduction adventure that gives your PC's a reason to come to the city and also serves as a kind of tour around the city. The map is GORGEOUS!!! I can't wait to break this out at the table!!
Thanks to my love of comic books, I've even started to think of an NPC that I will insert into Freeport that is a mix between Batman and The Punisher. He will give the poor and downtrodden hope, and make the wealthy, powerful, and corrupted types (of which there are MANY in this book) tremble with fear!!
Freeport for the win!!
