This has lots of useful references, tables, and maps. The adventures are mostly interesting, although a couple of the Hook, Line & Sinker Adventures are too simplistic and one of them is just bad guys take over a village and the villagers ask you to help(thanks Siembieda I couldn't have though of that on my own), but there are several that are interesting and fairly complex.
The only real negative is that the is not the best quality, it is still readable and most of the text is fine but some of the smaller text in the reference tables is fairly hard to read and many of the pictures have odd patterns of fading on them.
Overall this is a mediocre scan of a good GM reference set.
