Definately a great Black Isle game which deserves to sit in such high tiers as Fallout 1, Fallout 2, and Arcanum.  The story makes playing an Immortal fun for once (so read up, Soul Reaver makers).  The characters are imaginative and deep(and you can talk with the other characters in your party to enhance the story).  Find your journal, learn of your past, and for god's sake, use the sphere.
