I agree with you. I would rather be informed whether my actions have any profound long-term consequences or not. Personally I don't think the game is worth replaying all over, just to see minor differences of dialogue or some alternative outcome quest-branches.
I have spent over 150 hours playing Skyrim and there are so many more things I can do. For instance right now I can't decide whether I should keep playing my 41 warrior and finish as many side-quests as I can, including all of the guilds, or if I should start another character to take some seperate paths. The problem is that with the new character I'll have an empty bag and an unexplored map which limits my fast travel options. Sigh...
I have a similar amount of played time, however I find myself in a situation where...I feel less and less inclined to play, as I run into issues or come upon documented quest chains that require patches to correct and make completable. I find the game has zero actual replayability, even their hyped up radiant story system is not as random as they touted it would be.
You can literally see just about everything there is to see in the game with a single character, and the combat is not entertaining enough alone to keep me playing. I wanted to like the game, I really did, but I suppose I should not have marathoned Dark Souls and Fallout New Vegas directly before hand.

900+ hr's, 7 different characters and I've redone the MQ 2 times, the companions 3 times.
The game is what you make of it. I'll probably be playing it for a long time to come, though I probably will take short breaks here and their to play other games.
Of course I have specific goals for each of my characters and don't try and do the whole game with one. Which would I think make combat boring after awhile as the character gets stronger.
Each to their own though.
Edit: I should have put in that I have done every other questline at least once except DB which I am just starting.
