Besides adventures what is the best place to get info on the pathfinder world itself.
Right now, you have two main choices--Pathfinder Chronicles: Gazetteer or Pathfinder Chronicles: Campaign Setting.
I recommend the Gazetteer, for the following reasons:
* The Gazetteer is more affordable
* The map that comes with the Gazetteer is more accurate
* The Campaign Setting is being updated, and will be re-released in August as Pathfinder Campaign Setting: World Guide—The Inner Sea
Besides adventures what is the best place to get info on the pathfinder world itself.
At present, the Pathfinder Chronicles Campaign Setting, which will be updated with the coming release of the Pathfinder Campaign Setting: World Guide—The Inner Sea. Buy the latter. Beyond that, you get down to specific focused books that are found throughout the Pathfinder Campaign Setting product line. There are some shorter (and sometimes more player-focused/friendly) books in the Pathfinder Companion product line. You can also find lots of information online at the PathfinderWiki.
