The book "Magician" by Raymond E. Feist, which this game came from, is a great read and interesting in as much as the book came after and grew out of a long-running RPG campaign, if I remember correctly.
I always enjoyed the political fantasy spin-off series Daughter of the Empire by Janny Wurts more, though. :D
And yeah, the Empire trilogy is probably the best of his (co-)work.
