You are therefore ultimately forced into adopting the mental sock-puppet roleplaying mode, once you come to the inevitable realization that the game itself certainly isn't going to provide you with any of those interesting varietal experiences, once you've burned through the limited and quite mediocre 'RPG' content that's included in it.
Me and my buddies had wild fun inventing cowboy vs. indians scenarios in the backyards and playgrounds when we were in gradeschool... when all we had work with were some long sticks and our imaginations. That's pretty much where the devs leave us in Skyrim, once you've ogled all the scenery and the done 'n gone main quests are used up. Sure, I could imagine I'm some insane thief who only wears a loincloth and only steals mammoth cheese from giants on odd tuesdays... but frankly, I'd rather have the game made well enough so that I'm not forced to go that route just to have something semi-interesting left to do. I thought I paid for more than just a long, pretty stick.
Not every playthrough is the same. You don't have to do everything with one character, that was one of the downfalls of Oblivion, in my eyes. It was too easy to do everything in one playthrough. Hell, you don't have to do them in the same order. Start again, ignore certain questlines, etc. just stop complaining that it's boring. Stop blaming Bethesda for making a substandard game when you refuse to do something to make it more interesting that would rememedy it just because you "shouldn't have to because it's their paid for responsibility"
