I just got my copy today, and all I can say is 'Wow'.
First of all, this book is
solid. I'm talking the crack-a-bear's-skull type of solid. I think the law requires that I register this as a deadly weapon.
Just from a cursory glance, I have to say that I really like some of the concepts I've seen so far - The Origins (Talents and Specialties) and the Class Core Abilities just to name two. Also, it seems that AEG tried to keep the flavor of the spy/modern action genre throughout every part of the book (that I've seen so far). For example, the feats. Instead of just some run-of-the-mill name, we have feat names such as 'Too Ugly To Die', 'Rock and Roll!', and my personal favorite (and probably will be my group's favorite too), 'This...Is My Boomstick!'. The section on play styles is also good, giving guidelines on how to run games from standard Spy Games, to military SpecOps, and to Westerns. The art is great, though I would've liked to have seen a few more illustrations of gear (but that's really only a minor quibble).
All in all, I am
extremely happy with this book, and I'm looking forward to getting more supplements for Spycraft.
The only problem I have now is: What do I run first?
Spycraft, or
Dark Legacies?
P.S. Sorry if this sounded like a mini-review, but I am
really liking this book...I had to preach it to the masses!

Great job, guys!
