In a novel, the story is the only thing that matters, and Bioware's are simply better.
Opinions would differ on that, obviously. I think Skyrim portrayed the Empire-Stormcloak dichotomy very well, especially in light of the growing Thalmor threat on the outside of that war.
Whereas DAII's portrayal of the Mage-Templar conflict was decidedly... rushed.
Skyrim is a shallow world with shallow characters. Any "story" is hampered by a complete lack of effort on the part of the writers to make you give even half a crap about the world or anyone in it. What do I care if Alduin eats a bunch of cardboard cutouts?
The Dark Brotherhood's characters are not shallow. The Thieves' Guild's characters aren't shallow. The Companions aren't shallow, especially Aela. Ulfric and Tullius aren't shallow characters. A lot of other characters aren't shallow. Paarthurnax is not shallow. All of those things have a good/great story behind them.
I think it's a bit unfair to expect you to be able to get to know every single person in the game in extravagant detail just so you can care about the world. The DA series doesn't even do that. Hell, people on the DA forums will defend characters who have
just as much characterization -- or less -- as some of Skyrim's characters, possibly even citing them as some of their favorites.
The Elder Scrolls series has been churning out the same simple stories over and over and over again for decades, like a magazine repeating the same celebrity gossip over and over again. The faction quests are particularly egregious examples.
From what I know of the ES series, no, they have not. Skyrim's main story is not the same as Oblivion's. They're similar in that they're save the world stories, but they are not "the same simple stories" because they have different reasons for happening, different characters as a part of the main story, and so on.
And while I can't comment on the faction quests, I highly doubt Oblivion had the same exact stories as sKyrim's factions do.
