What an awesome product. I have the hardback book as well, but having the PDF just seemed like a must have to compliment the paper book. This has fasone of my favorite games. The Ubiquity system that this setting uses is very easy to understand and learn in about 5 minutes.
Like: What's not to like, it is well done, well written and has a beautiful layout.
I highly recommend this book to anyone want a change from the ho hum of D20.
