Crescent City, built on the ruins of what we know as Chicago, is the default 'home town' of the Brave New World game setting, and this book sets out to inform characters about the place in which they live through the by-now familiar format of an extensive series of in-character web pages.
If you want to base your game in Crescent City, or at least have the characters visit there, this is a useful resource... even if the authors of the webpages have the exact breezy, chatty tone as the writers of all the other webpages in other books in the series. Must be a style taught in the leading web writing schools across the Brave New World, I guess! Never mind, let's see what they have to say.
It's a lot more than a street map or a gazetteer. In fact there are only a few wide-area maps tucked away in the back of the book, unless you count a plan of New Alcatraz. There's history, starting with the battle that destroyed Chicago (and what brought that about, a quite tragic tale of revenge) and how the city that's there now grew out of the very ashes, built by a single corporation and governed by an appointed mayor (as you might expect given the permanent state of martial rule that exists in America). There's plenty about the deltas who live there now - legally and otherwise - from the Delta Prime HQ to a hotbed of Defiance supporters and even the gaol of New Alcatraz in the middle of the lake that has been specially built to hold criminal deltas.
Next comes an area by area description of the city, with a wealth of background to make it come to life... and, if you're the Guide, to spawn plot ideas just about whatever manner of game you intend to run. Lots of people who might interact with the party, hire them or oppose them, places to visit and so on. Some maps would have been nice, but if you need them and have the time, the descriptions are enough to come up with at least a rough sketch of the lay of the land.
Then comes the player material, with a selection of new power packages. These are all linked in some way to living in Crescent City (although most if not all could be used elsewhere). Each comes with an archetype to use as-is or provide inspiration for your own character taking that power package.
The Guide section, after remarking that the Guide is welcome, indeed encouraged, to stamp their own mark on Crescent City, then as usual lifts the lid on what has gone before and tells it like it is. There are quite a few Crescent City based adversaries to throw at the characters too.
This is followed by 'The Teleterrorists' which is an adventure set in Crescent City ready for you to run. It's designed as an introduction to the City as well, so would suit a party arriving from elsewhere or as the start of a new game. As a result, there's plenty going on and it gives the characters a good chance to get embedded into the place quickly... with the climax occurring at a game of deltaball (American Football for the superpowered).
Finally, the Author's Afterword contains snippets of personal information and explains that since the move to AEG he's not writing every word himself but getting contributions, particularly in the shape of well-defined profiles and stat blocks for NPCs (which he doesn't like writing much!).
Overall a very useful tome if you intend your game to visit or be set in Crescent City, as well as the first actual scenario to play.
