Kingdoms of Amalur certainly felt more like busy work then fun, I quit halfway through.
Skyrim also got boring... after 60 hours, not a big problem there. Still a lot of side quests could have been better and some should have just been left out. I should have done the main quest sooner, it wasn't much fun after I had already gotten bored with the game.
Fallout New Vegas had the balance just right. Dragon Age: Origins was very good too. Or you can go with pure exploration like in Dark Souls, my favorite this gen.
