This is an amazing book, the classes are well designed (though not necessarilly well balanced) and the races are departures from the stereotypical norms. Class / Race abilities are amazing. For someone who likes D&D 3.0 or 3.5 this book is a blast.
The other reviewer says that this is an almost unreadable scan, I disagree, I haven't had any problem with reading it. Some of the pages were at a bit of an angle when it was scanned in, however it is readable without any difficulty.
