Beginning in 2002, Paizo took over publishing
Dragon and
Dungeon magazines, which were about the
Dungeons & Dragons (
D&D) role-playing game, under contract to the game's publishers
Wizards of the Coast. Wizards of the Coast chose not to renew the contract in early 2007 and Paizo began publishing the
Pathfinder periodical line as a replacement. In August 2007, Wizards of the Coast announced the pending release of the 4th edition of
D&D (4e), which replaced version 3.5 (3.5e). Many of the staff at Paizo were concerned about the more restrictive
Game System License under which the 4th edition was being released, compared to the earlier
Open Game License (OGL). They had also not been provided with a copy of the 4e rules. During their time publishing the magazines, Paizo developed their own adventure path,
Shackled City, using the 3.5e rules, originally published in segments within
Dungeon over several issues and later collected for release in a standalone project. Due to the uncertainty with the 4e rules and license, Paizo developed a new adventure path called
Pathfinder, designed to bridge the gap from 3.5e to 4e, but still based on the 3.5e rules as they knew the current 3.5e license allowed for third party material that was compatible.
Jason Bulmahn, one of the Paizo designers, had envisioned a modified ruleset from 3.5e with
Pathfinder in mind, and when he presented his idea to the company, they decided to go all in to make a wholly new ruleset named the
Pathfinder Roleplaying Game, with Bulmahn leading its design. Announced in March 2008,
Pathfinder was designed over the course of a year using an open
playtest model, where players could try the system and post their feedback on Paizo's website. The first
Pathfinder rulebook was released in 2008. Paizo was not sure how
D&D fans would react to a derivative project, nor how Wizard of the Coast would respond. Preorders for the first printing were sold out before Paizo had received their books, and they quickly issued a second printing to meet the high demand. the first edition of
Pathfinder is a modification of the 3.5e rules and is intended to be compatible with the older game. Players register their characters on Paizo's website, allowing players to use their characters in different play sessions and different groups while continuing to earn experience, money and prestige points. After a session has ended, the player will receive a chronicle sheet, listing what has been earned during the session. The player will use these chronicle sheets to log this information on the website.
Second edition In March 2018, Paizo announced that it would be conducting a playtest for a second Edition of
Pathfinder. Paizo announced in May 2018 that it was working on
Pathfinder Second Edition to refine elements of the rule set to reflect feedback and clarification on the original system over the prior years. The preliminary ruleset was published in August 2018 as
Pathfinder Playtest so that players could test out and provide feedback. The final rule set was released on August 1, 2019. A 6-volume Adventure Path was released for Second Edition, designed to take player characters from 1st to 20th level. Among key changes in the second edition is a streamlined action economy. Each round, each character can perform up to three actions on their turn as well as one reaction on their own turn or another character's turn. Most basic moves, such as moving across the ground, drawing a weapon, or making an attack cost a single action, while more complicated maneuvers may require two or three actions. The rules around magic items have been changed to discourage players from hoarding too many items and instead encouraging them to seek out more powerful equipment. Finally there has been a broad change to all number scaling of skills, armor class, attack rolls, saves, and difficulty classes. All these numbers now scale 1-to-1 with a character's level plus a stat plus a bonus between two and eight depending on their proficiency. This results in extremely bounded values when compared to the first edition. Stats have also had their range lowered when compared to the first edition. In October 2021, Paizo announced a partnership with
Demiplane to provide Pathfinder Nexus; the online platform provides a digital rules and lore compendium for
Pathfinder Second Edition, character creation and management tools,
matchmaking, and
video chat functionality. An
early access version of Pathfinder Nexus, titled Pathfinder Primer, was launched at the time of the announcement.
Second Edition Remaster In April 2023, Paizo announced a set of four new primary rulebooks (
Player Core,
GM Core,
Monster Core, and
Player Core 2), to be released over the course of 2023 and 2024. Collectively referred to as the
Pathfinder Second Edition Remaster Project, these four new books are intended to fully replace the existing four primary rulebooks (the
Core Rulebook,
Bestiary,
Gamemastery Guide, and ''Advanced Player's Guide'') which will not be reprinted in the future. In addition to incorporating extensive errata based on player feedback, these new books (and all future Paizo publications) would be published under the new
Open RPG Creative License (ORC), rather than the previous OGL, due to
significant controversy over the license earlier that year. Because of this licensing transition, certain game elements (such as some spells, magic items, and monsters) inherited from the Dungeons & Dragons 3.5 SRD had to be either renamed or replaced, or in some cases fully removed (such as
alignment, or the
eight schools of magic). Despite these changes, the new books remain backwards-compatible with existing Second Edition supplements. == Supplementary material ==
