And it is a shitty ending cause you don't do anything. The game might as well ended when you close the huge gate. The final battle is just running around a ruined Imperial City. In Morrowind you alone destroy the Heart, even if you don't actually directly kill Dagoth Ur. And though you are aided in the final fight against Alduin, and its basically every dragon fight ever, atleast you actually fight him.
Oblivion you just deliver Martin to the center so he can steal the glory in a cutscene.
I'll agree with you that vanilla Oblivion's ending lacked the Big Damn Hero ending that prior games/expansions like Morrowind or Bloodmoon had. I felt they more than made up for it [footnote]and in the process, circumvented the reasoning for this type of ending; possibly this was a response to Oblivion lacking the "big fight" ending.[/footnote] with The Shivering Isles though, as you end up a Daedric Lord after nut-punching another Daedric Lord, Jyggalag, mano-a-mano. That said, I think you off a bit about who the real hero was. Martin was just a hand grenade. You found him, you molded him and you delivered him to defeat the legit, undiluted, oh-fuck-we're-all-dead form of Mehrunes Dagon. In Bloodmoon, you only fight an avatar of Hircine, and its a bad-ass. It's not hard to believe that it would be nigh impossible to try to toe-to-toe Mehrunes Dagon, hence the creation of the walking, talking, Holy Hand Grenade you use to blow him up.
But I can see how it could be disappointing or viewed as anti-climatic.
I also liked how your actions were viewed in later games. One of the things I like seeing is how the history of TES changes via the books in the game. Its fun to see how history gets most things right, but some things wrong, and embellishes some parts. Like real life history, its not as accurate as we would imagine it to be, and reflects the perception of the writer.
