Moody old mage.
At the end, it felt like a chore to me too (though, TBH, when a game nears the end I always feel them to start becoming a chore because I becomes itchy to see the end itself, one of the reason I hate the habit of having a "last huge dungeon"), but I think the problem mainly comes from what I said before : the game becomes too easy due to a bad balance. I used crafting and was basically an unkillable engine of destruction, which is fine for a while but makes the killing much less satisfying (no point in becoming stronger, bored to plow through foes, etc.).So it felt like a chore, and there must have been a reason for it.
Which is the reason I strongly advice not to ever use crafting. And not to be afraid to mess up your build too (it's just one reset if you don't like it anyway). Too bad the game isn't moddable as a TES, as it's just one balancing act away from being a true gem.
Anyway, I tend to like and respect huge game with huge content and in which you can sink for tens of hours, so it's a big plus for me. I understand many people ends up overwhelmed or tired instead of exhilarated instead. Definitely NOT a game for the short-term, true.
