I just recently picked up the Knights of the Nine downloadable content collection for The Elder Scrolls IV: Oblivion, and I'm thoroughly enjoying it. In fact, it has sucked me back into the Oblivion world, so most of my free time is now spent questing with a brand new character (a Breton I named Tristram). Included in the collection is the brand new Knights of the Nine quest line, which supposedly adds an additional 9 to 10 hours of game play. Also included are a number of add-ons that were previously only available for purchase online: the Wizard's Tower, Vile Lair, Thieves Den, Mehrunes' Razor, Horse Armor pack, The Orrery, and a collection of spell tomes (my favorite add-on so far). I was lucky enough to pick it up for only $9.95 at Circuit City (the same day I wrecked my car), but it normally retails at $19.95. If you're a fan of Oblivion (and who's not?), I highly recommend the collection. So far, it's been a blast.
