Dragon Age: Origins, Awakening, Titan Quest, and BioShock on Sale

Another day in the Steam "Perils of Summer" sale is upon us, with the latest batch of deals including Dragon Age: Origins and Dragon Age: Origins - Awakening for 40% off, Titan Quest Gold for 75% off ($4.99), BioShock for 75% off ($4.99), and Thief: Deadly Shadows for 85% off ($2.99). I realize the Thief series is largely outside of the RPG genre, but I still think that's a great price for a game that will no doubt appeal to patient FPS/RPG fans.
