I don't agree, Daggerfall was as far as I care a totally failed concept, imagine traveling all through a whole country on foot, with extremely undetailed maps that show you standing at the same pixel even if you've moved several miles, and a max visibility distance of 30 meters or so (in the real world, it's up to several miles even with the unaided eye). Add that everything looks the same and you see why I never found it any fun. Morrowind is much better IMO.
But the main point is neither is anything like Korax' Heritage, KH is all about Hexen-style action with an epic RPG scope, not about picking flowers and concocting potions.
