If you liked Sengoku, you will simply have to buy this one, the perfect expansion for the Shinobi! Absolutely great both in style and usefulness.<br><br> <b>LIKED</b>: all, a great work, second only to the main manual of Sengoku <br><br><b>DISLIKED</b>: nothing<br><br><b>QUALITY</b>: Excellent<br><br><b>VALUE</b>: Very Satisfied<br>

Even though I have the print version, I still ordered the PDF since it's easier carrying around my PDA or Laptop with the PDF version than all of my books.

Well I will be brief in my assessments. Basically this product is a very accurate and historical factbook on the real ninja of Japan. Of course it include a lot about the mythological powers of the ninja but basically it is a down to earth sourcebook on the ninja. I personally would buy it just for the info even if I never played a RPG in my life. It's a textbook on ninja.

Decent historical work, but doesn't grab you and hold you.

All you need to know about the Ninja of medieval Japan. It even has comments by the Sensei of Bujinkan, the Ninjutsu association - to which I'm about to belong...

Great book by GRG. The definative Ninja. The Sengoku line has been excellent source material.
