Turbine has filed a lawsuit against publishing partner Atari in New York courts for a breach of licensing agreement all centered around Dungeons and Dragons Online. The two companies are locked in a legal battle regarding accusations including failing contractual obligations and wrongful termination of agreements.

The court documents filed on Monday paint the picture of a long chain of grievances against Atari made by Turbine, starting with lackluster support all the way back when Dungeons and Dragons Online: Stormreach launched in 2006. Turbine asserts that Atari has failed to maintain their obligations as the publisher of the game while still holding onto the licensing for Dungeons and Dragons. These obligations mostly include the marketing aspects of the game, such as commercials, advertising, retail box creation, retail promotion, and cross-promotion with other Atari products. (Fans of the game will remember the very lackluster marketing campaign at the game's launch, especially when compared with Champions Online's marketing, another Atari-backed game.) Because of these failures, Turbine has had to step in and become the publisher of the game in North America, costing the company millions of dollars.
