The Pathfinder Roleplaying Game (abbreviated PFRPG) is a fantasy roleplaying game (RPG) first published in 2009 by Paizo Publishing. It extends and modifies the Revised 3rd edition Dungeons & Dragons (D&D) game rules published by Wizards of the Coast under the Open Game License, and was designed over the course of a year with the help of gamers who could download the playtest versions of the game, try the system and post their feedback on Paizo's website. The PFRPG supports Pathfinder adventure paths, as well as other works set in the Pathfinder Chronicles Campaign Setting.
