Matt Chat 246: Robert Sirotek on Wizardry 1-6
Lots of great stuff in this episode, particularly if you're aware of Sir-Tech's history and read between the lines here. I can't go into detail though (promised Robert!).
Some folks have been quick to disagree with him that Wizardry 6 was the first sci-fi/fantasy blended RPG. However, it does lend credence to his earlier claim that Sir-Tech's developers ignored Garriott's games and were never directly influenced by them.
