Reynolds began working for Time Warner Interactive in 1994, to develop their America Online and websites.[1] Reynolds first entered the role-playing game industry in 1995, when he was hired by TSR as their online coordinator,[1] beating out Bruce Cordell for the same position.[2] According to Reynolds, "I had two goals: to get TSR a website, and to change the company's then-restrictive online policy to something more reasonable."[1] When TSR was bought out by Wizards of the Coast, Reynolds moved to Washington and worked on Wizards' pre-existing website.[1]
Reynolds considers one of his greatest achievements of this time to be the fact that he got TSR/Wotc to relax its "draconian" online policy—enforcement of which in the past was the cause of much bad blood between the company and fans.[2] Wizards of the Coast had a much more open online policy, so Reynolds applied for a job in the company's R&D division as a game designer. He designed such products as The Scarlet Brotherhood for AD&D, Beyond Science: A Guide to FX for the Alternity game, and The Green Goblin's Guide to Crime for the Marvel Super Heroes Adventure Game.[1] Reynolds also did some design work such as writing RPGA adventures and contributing to Children of the Night: Ghosts.[citation needed]
By 1998, Reynolds had left his web position and was working full-time for WotC as a designer as part of "Team Greyhawk," the creative team tasked with revitalizing TSR/WotC's oldest campaign setting.
Reynolds also contributed to the 3rd edition D&DMonster Manual, introducing some new creatures such as the krenshar.[1]
After Wizards of the Coast
Reynolds was laid off from WotC in 2002,[citation needed] and afterwards formed his own self-publishing company, "Sean K Reynolds Games."[citation needed] He continued to freelance in the d20 industry while working as an IP developer at Upper Deck.[citation needed] Reynolds was let go from Upper Deck in 2008 and contacted Erik Mona at Paizo Publishing looking to do freelance work, and learned there was a job opportunity due to developer Mike McArtor leaving.[3] In July 2008, Paizo hired Reynolds as a developer on the Pathfinder Roleplaying Game.[citation needed]Jason Bulmahn has described him as a "critical part of the design team".[4] In March 2014, Sean left Paizo to move to Indiana[5] and in May 2014 he announced that he was returning to Seattle and Wizards of the Coast for a contract position managing their third-party licensing.[6]
The Forgotten Realms Campaign Setting won the Origins Award for Best Role-Playing Game Supplement of 2001.[7] It made the Amazon.ca bestseller list at number 47 in September 2002.[8] Reynolds identified the Forgotten Realms Campaign Setting as his favorite individual product that he had worked on as of 2009, stating that it "was a huge amount of work but was so worth it because it is a great product".[9] In May 2003 his book Races of Faerûn (co-authored with Matt Forbeck, James Jacobs, and Eric L. Boyd) landed on the same bestseller list at number 42.[10]
