This is my first foray into games using the Powered by the Apocalypse system, and I have to say, I am very impressed!
As an introduction to role playing games, this little book ticks all the marks: it is clearly presented, the rules are easy to understand, it encourages creativity, and does not get to crunchy. By explaining that each individual DM (dragon master) should interpret and expand the moves system to match the game they want to play (and providing direct references to the inspirational materials), this game is perfect for the beginner and experienced game master alike.
As a world book, this product could not be better. It paints a picture of a beautiful, diverse, and accepting world ruled by dragons and inhabited by creatures that are only limited by the imagination of the individuals playing the game. The constant reminders to keep play rooted in the traditions of the realm- without expressly defining those traditions - provides a creative freedom that is rarely seen in sourcebooks that define a world.
I would recommend this book to anyone with an interest in role playing, dragons, or especially those interested in role playing dragons, as an invitation to participate in a vibrant and special world in which both external and internal exploration are not just possible, but encouraged.
