Jason Bulmahn has coordinated the world’s largest organized play D&D campaign for the RPGA of Living Greyhawk, later joined Paizo Publishing as the managing editor of Dragon in 2004.
He, in 2007, took over as lead designer of Paizo Publishing. Within two months of Wizards of the Coast’s August 2007 announcement of D&D fourth edition, he began working on a new edition of the d20 system that updated and polished the rules system.
When Paizo decided not to wait any longer to see how Wizards of the Coast would allow third-party publishers to support their new game, Paizo turned he’s side project into a complete RPG to give them their own set of core rules for the d20 game system; Paizo thus announced the Pathfinder Roleplaying Game on 2008. He is from then the lead designer of the Pathfinder Roleplaying Game.
He has also written or contributed to Pathfinder books such as Carnival of Tears, as well as Dragon and Dungeon articles and books such as Secrets of Xen’drik, Expedition to the Ruins of Greyhawk, Dungeonscape, and Elder Evils.
His RPG design credits include the Pathfinder Roleplaying Game Core Rulebook, Bestiary, Ultimate Guides, the Advanced Player’s Guide, the Beginner Box, and 2013’s Mythic Adventures.
His work has earned one Origins Award and numerous ENnie Awards, including Best Game and Product of the Year.
He is the publisher of Minotaur Games, a company dedicated to creating products compatible with the Pathfinder Roleplaying Game as well as card and board games.
Jason is one of the big authors in roleplaying games.
