I actually don't like later Bethesda games. Their last good RPG was Morrowind, but I like both Witchers a lot. And I usually not that much into looking for best graphics ever, I'm more interested in the story. Of course I appreciate good graphics, but that's not what makes it or breaks an RPG for me. Story however does, and both Witcher games are excellent in that regard. As for 3D and isometric, both have their place and there are great examples in both types.
