I love this book, it does Asian fantasy well. It gives enough to build on and mashes up a lot of Asian cultures into one fantasy culture so you can run it with many different feels. Just like they do white cultures in normal AD&D, they take Greek to Russian and roll it into a ball and put magic on it to make a fantasy culture that represents many views and traditions. It was the first book I ever read that made fighters more than just brutes in this book; they are artists, and poets. It sparked my interest in Asian cultures I hold to this day. If you are going to this book for facts about real word culture you won't find much, just like you won't find facts on any real world cultures in any AD&D book, but if you want to add Asian flavor and feel to a 1e game this is a good resource.
