I agree that the combat of Xenoblade is MMO like, but the main strengths of Xenoblade, the sense of scale to the world and the focus on exploration is far more reminiscient of an Elder Scrolls game. I preferred Skyrim's world.
I don't think Skyrim borrowed from MMOs at all. In fact, I think the game is quite stubborn in sticking to the Arena/ Daggerfall style gameplay, which predated modern MMOs by a considerable margn. Surprisingly retro, that Skyrim. I give Xenoblade full points for the combat system. That is way, way more interesting than Skyrim.
