I had pre-ordered the book, and the initial run had a bad binding process. I contacted Mongoose and they replaced it for free. The current runs have an improved binding that is more what I've come to expect from Mongoose Publishing. Some folks do not like the B&W illustrations, but I like the feel of the B&W. The appearance is very crisp, and the bulk of the book is packed with text, so those 400+ pages are not simply crowded with filler.
The 2nd Edition rules have been well-clarified and many contentions and confusing aspects of the Atlantean Edition have been cleared up. The classes, races and some of the mechanics have also gotten a new facelift, but the entire rules as is are 99% compatible with the vast amount of material that are out for the game, so that's a major plus.
As has been mentioned in another review, the Temptress class is now included in the core classes in the main rule system, and she has gotten a well thought out revision as well. Notably, in place of where the former temptress would have gotten Sneak Attack, the temptress in 2nd Ed now has various levels of Secret Art; With Secret Art, you choose between Politics (which allows you to choose Noble-eseque skills), Sneak Attack (which deals with Sneak Attack as well as allows some addition rules for distraction in melee), or Sorcery (which allows some access to sorcery spells, advanced spells, and special rules to gain power points)
Speaking of sorcery, some of those rules have been revamped, clarified and improved as well.
Overall, especially now that the binding issue is resolved, I applaud the second edition of the ruleset. It's much more concise and user-friendly. And unlike some of the other reviewers, I like the clean black and white layout and graphics. An excellent book!
