A very nice overview of the Golarion planes. It does give a short and evocative description of each plane and unique areas. The only reason I'm not giving this product a full 5 is that I wish they had devoted a few more pages to specific planes. Hopefully we'll see follow ups. Most planes are very familiar, although Maelstrom, Abaddon, and Axis have their own uniquely Paizo feel. Here's my vote for more Golarion planar fun, perhaps a few more books, each one spotlighting 2 to 3 planes.
I haven't had a chance to put this together quite yet, due to a shortage of ink. However, I have looked at it and the instructions in depth. I would definitely like to see more Pathfinder Terrain by Worldworks.
An excellent resource on elves in the world of Golarion. My only complaint is that I feel some of the nonstandard elven societies could have been fleshed out a bit more. In other words, a sourcebook detailing the ruins of Azlant, the Aboleths, and the elves of Mordant Spire would be greatly welcome.
An amazingly well written campaign setting. The book is mostly fluff, but the crunch is very well written, evocative, and balanced, while the fluff draws on some of the best fantasy concepts and giving them a fresh spin. I definitely recommend this title.
