I picked this up largely because in the wake of the controversy caused by Tournament of Rapists (from the same author) there was a pretty strong likelihood this item might not be long on the site. I think the subject matter is not unworthy in itself - because actual Japanese erotica is if anything MORE weird - but the execution could have been done better. For example, the text needs more organization and editing. As in, any organization or editing at all. Also, this is the second edition of an older title that was originally modeled around D20 Modern, whereas this "Unlimited" Edition is more like a travelogue of the various locations in the Black Tokyo version of Japan. Thus it doesn't have a lot of the game material (like feats) that used to be in the older version of the book and are now in other sourcebooks for the line. The book is not completely worthless, but the aforementioned issues mean that it's only worth picking up if you're really invested in the subject matter, namely the utter fracking weirdness of Japanese sex culture. Which in this case apparently means not just rape but scatology.
