Uses old D&D rules so no Witches or Maguses etc. The class builds are therefore not powerful enough for modern PF. They are also quite dull, far, far too many 5th level ranger guides and Dex based sword using rogue/fighter types. It is quite odd, they seem to account for about 50% of the characters.
A sequel is very much needed.
We need all the newer classes, and fill in chracters from other lands - Casmaron, Vudra etc. This is an area the book really shows its age - there are no proper Varisian or Sczarni characters and only one (fairly bland) Hellknight! Modern PF would probably have a dozen.
To its credit, the little picture portraits are great, and the mini biographies and boon hooks are of proper Paizo standard. It is hard to complain becuase this fluff is excellent, but the crunch lets it down and seeing as we don't even use those rules any more, it probably doesn't matter.
