Dungeons & Dragons Controversies - Business Disputes at TSR

Business Disputes At TSR

The game's commercial success led to lawsuits initiated in 1979 regarding distribution of royalties between D&D co-creators Dave Arneson and Gary Gygax. Specifically at issue were the royalties for AD&D, a product for which TSR did not acknowledge Arneson's intellectual property claims. Those suits were settled out of court by 1981.

Gygax became embroiled in a political struggle for control of TSR and disputes related to the company’s deteriorating financial situation in the early 1980s. The disagreements culminated in a court battle and Gygax’s decision to sell his ownership interest in the company in 1985.
