Oh right! Nice one. (Clueless about what he means.... Going insane.... Tell me!)
He did the actions that completed the main storyline.
And no, I didn't think the Oblivion ending was better. I hate playing single player games to feel like the tool of someone that wants to steal my thunder. WoW does this as well. An MMORPG, and yet a band of adventurers cannot do anything "good". Terenas Menethil's ghost essentially kills the Lich King. Maiev Shadowsong kills Illidan. Thrall kills Deathwing. We enable it, but holy crabcakes let *us* do it. Heck, they even retconned Nefarian and Onyxia's deaths(Deathwing's two kids) in the lore to reflect King Varian Wrynn of Stormwind(who was missing entirely until recently) killing them. It's ridiculous. EQ2 at least keeps the "brave band of adventurers have defeated Norrath's biggest threat" motif.
Then I go play Oblivion and get angry every time I see Martin do his thing. /rage
