Some quick searching provided information that the game in question ended up as Demise: Ruse of the Ku'tan, but during development is was called Infinite Worlds and Mordor II: Darkness Awakening (the game is related to Mordor: The Depths of Dejenol). In another forum, a user asked about a role-playing game called Infinite Worlds, allegedly developed by Interplay, which that user has a beta of but could not find a full version.
