Hasbro also alleges that Atari was misleading about the terms of the sale to Namco Bandai from the onset, per Forbes; it’s suing for damages and termination of the licensing agreement.

Both parties say that they’ve tried to come to terms over the allegations out of court: “We have been working for several months now to reach resolution with Atari, and they have left us with no other choice than to pursue legal action,” said Wizards of the Coast president Greg Leeds, in a statement.

From Atari: “Atari has [invested] millions of dollars into numerous critically acclaimed and commercially successful [D&D] games that have generated significant revenue for Hasbro. Hasbro has resorted to these meritless allegations, in an apparent attempt to unfairly take back rights granted to Atari. Atari has sought to resolve the matter without cooperation from Hasbro. We regret that our long-time partner has decided to pursue this action. Atari will respond appropriately through its legal counsel in court.” Release.
