to DarkFox: What is the question? Are you asking what Alien Saga is? Alien Saga is a DVD on its own, not "included" anywhere else. It was released shortly prior the release of Quadrilogy and Fox is not involved in it at all (not counting the copyright). The main feature comes from TV, the bonuses from Fox's archive. I suppose that they made a deal with Lauzirika's (Quadrilogy) team to avoid duplicating the bonus material between Saga and Quadrilogy. Thus, effectively, it is a 10th disc to Quadrilogy. SRP approx 15 USD.
