You didn't miss much. The horse armor was a joke, and the other DLCs were meh at best. Shivering Isles and Knights of the Nine were the only real DLC to care about.
As for the Skyrim DLC, I agree with you guys; console exclusive rights is a ridiculous policy and just caters to profiteers and not the players.
That said, I'd like to segway to speculation as to the possible DLC for Skyrim. Now naturally we don't even know details about the game itself yet, so that limits our possibilities, but I've noticed a pattern with the DLC of both Morrowind and Oblivion so far that might give us a clue as to what we can expect with the main expansions/DLCs of Skyrim: in both Morrowind and Oblivion, there was one expansion that centered around and involved Daedric lore (Hircine in Bloodmoon and Sheogorath in Shivering Isles), and another that dealt with some regional plot device (Helseth and Alamalexia in Tribunal and the Knights of the Nine in Oblivion). Therefore, it could be safe to assume that Skyrim will also include two expansions/DLCs that center on a Daedric prince and a local lore.
Anyone have any ideas or hopes?
i thought knights of the nine was gay, then again i only roleplay evil characters, and HELLO!!! what about DEEPSCORN LAIR!!!! that was the best lair in the game besides benirus manor's necromancer lair, and then again i only roleplay evil characters
EDIT: what they should add as a DLC is playable lich and quest/necromancer lord
