Excellent urban fantasy supplement! The setting is well-explained, with clear delineation of things that are possible and those that aren't (there's for example a table for which kind of characters can use what kind of magic, which was really useful).

Best of all, it doesn't assume you're going to use the default setting. Which is a very realistic approach by the author...the odds of me running a game in the default setting approach 0, and even if I did, it would probably be situated in the areas that the game doesn't assume to be the major focus of interest. What can I say, I simply find the EU, or the Vampire-controlled regions of Russia's Far East, to be much more fun!

But then the game covers those areas as well, just in less detail. So I can do that as well. And if I decided against it, I can still use it as a basis for "general urban fantasy", by sticking to the magic (the changes make it much closer to the genre's expectations) and character types! The half-fae, in particular, are golden... Admittedly, I don't like the lycanthropes as presented in the book nearly as much as the rest of them, but I'm sure I can change them to be to more to my liking - without major effort.
