Dune: Chronicles of the Imperium (2000): Last Unicorn Games; role-playing game set in the Dune universe. Delayed by legal issues and then a corporate buy-out of Last Unicorn by Wizards of the Coast, a "Limited Edition" run of 3000 copies of a core rule-book was initially published, pending Wizard of the Coast's conversion of the game to its d20 role-playing game system and a subsequent wider release. The company later announced that the game would be discontinued.
