Sierra only published it, Throne of Darkness was developed by Click Entertainment.
edit:
Found this info on a site, hope it helps.
"Click Entertainment is a new development house formed by Doron Gartner and Ben Haas, two members of the Blizzard dev. team responsible for the hit action-RPG, Diablo. The company's first project is Throne of Darkness, an action rpg set in feudal Japan."
