Career
Cook responded to an ad in Dragon magazine for a game designer position at TSR. After writing a sample module section and completing the designer test that the company then used, Cook became the third full-time game designer hired by TSR. Lawrence Schick was head of design and development at the time and brought Cook on board during a time of substantial growth at TSR. : 11 Cook later became Senior Designer. "Game designing is hard work [...] but everything worth doing is hard work. The important thing is to do it well, and to have fun while you're doing it." Cook created role-playing games, modules, family board games, card games, rulebooks, and party mystery games.
He created the Partyzone mystery game line and The Spy Ring scenario. The first Partyzone game was named one of the Top 100 Games of 1985 by Games Magazine. Other notable works for TSR include the role-playing games Conan the Barbarian, Crimefighters, The Adventures of Indiana Jones, Star Frontiers, Sirocco, and Escape from New York. Cook also wrote several influential early adventure modules for D&D and AD&D, such as A1: Slave Pits of the Undercity, I1: Dwellers of the Forbidden City, X1: The Isle of Dread, X4: Master of the Desert Nomads, and X5: Temple of Death (the 'Desert Nomads' series). Other module work included CM4: Earthshaker!, AC5: Dragon Tiles II, AC2: D&D Game Combat Shield, B6: The Veiled Society, CB1: Conan Unchained!, and M1: Blizzard Pass for D&D and AD&D, and Top Secret module TS005: Orient Express and Boot Hill module BH2: Lost Conquistador Mine.
After Tom Moldvay wrote the second edition of the D&D Basic Set, published in 1980, Cook developed the Expert Set to take characters beyond third level. : 11 Cook was the primary author of the original Oriental Adventures, : 17 ostensibly under the guidance and direction of Gary Gygax, which among other things introduced the concept of non-weapon proficiencies into AD&D, and he designed the far eastern setting, Kara-Tur. Cook, with Jim Ward, Steve Winter, and Mike Breault, co-wrote the adventure scenario that was adapted into the game Pool of Radiance. Cook was the lead designer on the 2nd edition of Advanced Dungeons & Dragons role-playing game. : 22 In Dragon #118 (February 1987), Cook wrote a column titled "Who Dies?" in which he discussed which character classes may be thrown out in the revision, with the intention of provoking a response from readers. : 22 Cook was also the lead designer on the Planescape campaign setting. When TSR was looking to replace Spelljammer after the setting ended, Slade Henson suggested a new campaign setting could be built on the first-edition Manual of the Planes; after the idea sat dormant for a year, Cook picked it up and invented Planescape as a result. : 26 One reviewer described Planescape as "the finest game world ever produced for Advanced Dungeons & Dragons".
Cook left TSR in 1994 to work in the field of electronic media.[citation needed] He worked on the game Fallout 2. He was the lead designer on the 2005 City of Villains computer game for Cryptic Studios. : 153 After he left Cryptic, he joined Cheyenne Mountain Entertainment as the lead systems designer for the video game Stargate Worlds. In 2001 he was inducted into the Origins Hall of Fame.
In 2013, Cook worked as Content Designer at ZeniMax Online Studios on The Elder Scrolls Online. With the release of the Elsweyr expansion for the game in June 2019, Cook was credited as a Senior Product Owner for Bethesda.Net.
