In relation to past Eclipse Phase products, I'd place it somewhere below Sunward and above Gatecrashing. In relation to any other RPG product, I'd place it in my cart to buy immediately. :) If you're looking at this review, you've presumably already read the core book and fallen in love with the setting. This book is more of the same in the best way possible, brilliantly researched "fluff" to bring colour and life to new corners of the setting, and a wee bit of new "crunch" to go along with it.
