In 1988, he was introduced to GURPS and became an active on USENET. While working on a list of GURPS supplements, he was contacted by Steve Jackson Games for some corrections. This eventually led to a job as the first coordinator of GURPS errata which he stayed at for five years. During his time at Steve Jackson Games, Johnson authored, co-authored, or contributed to seven books (see Bibliography below) for the company's GURPS role-playing game. He also served as development coordinator for the company's Knightmare Chess 2nd edition card game.
Johnson authored or co-authored several books for Steve Jackson Games. One of these books, GURPS Monsters, won a rating of A in a review published in Games Unplugged. John G. Snyder of gamingreport.com rated the book at 4 1/2 stars, saying, "You will be pleasantly surprised and not a little disturbed." Freelance Writer Craig Oxbrow says in a 2001 review of the book for rpg.net, "GURPS Monsters is a wealth of ideas and inspiration for monsters as characters," and that it "will see use beyond the GURPS system." Kenneth Hite from Out of the Box reviewed Johnson's book GURPS Japan: beauty, terror, and adventure, 2nd ed. in 1999, concluding that "medieval Japan, broadly defined, is suddenly one of the most solidly playable milieux in Gaming."
Johnson's gToons game proved popular among children, with more than 250,000 registered online users within the first month after the game's launch. The game was introduced in 2002, when the growth of Cartoon Network's website (Cartoon Orbit) traffic was far outpacing the Internet in general, yet the website was still lagging behind Nickelodeon. Cartoon Orbit was the first children's TV website to introduce digital trading cards related to their programming in 2000, but Nickelodeon surpassed them with a similar approach six months later. gToons was intended to help Cartoon Orbit regain their lead in internet traffic among children. After looking at early usage data for the game, Cartoon Network's Justin Williams commented, "Competition really is just as much of a community-builder as collaboration." Three months after gToons was released, Cartoon Network executives were planning spin-off products and merchandising from the game. At that same time, Nickelodeon announced that it too would also be launching games based on its digital trading cards. MIT professor Henry Jenkins said in an interview with USA Today regarding online card games associated with children's TV networks, "what Cartoon and Nick are doing is just an extension of the Pokémón phenomenon."
