パスファインダーRPG
Jason Bulmahn coordinated the world's largest organized play "D&amp;D" campaign for the RPGA (Living Greyhawk), and then joined Paizo Publishing as the managing editor of "Dragon" in 2004. In 2007, Bulmahn took over as lead designer of Paizo Publishing, LLC. Within two months of Wizards of the Coast's August 2007 announcement of "D&amp;D" fourth edition, Bulmahn began working on a new edition of the d20 system that updated and polished the rules, and that he referred to as "a small side project". 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 Bulmahn'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 March 18, 2008. Bulmahn became the lead designer of the "Pathfinder Roleplaying Game".
