I just can't agree with much of this list. Not just with the rankings (The Witcher 2 doesn't belong in the top 10, never mind #2 - far too many flaws and Shadowrun Returns is mediocre - just look at the ratings) but there are too many omissions.
Where's an Ultima - especially Ultima 7 Part 1 and 2? U7 had perhaps the best RPG narrative up to that point and still is a great game to play.
Fallout 1, 2 and 3 should go on this list. All are better than NV.
IMO, Skyrim >>>>>> Morrowind. While Morrowind's setting was more exotic, the setting in Skyrim was perfectly grounded and the story far more compelling.
Diablo >>>> Torchlight. Hands down.
M&B isn't a role playing game. You have to stretch the definition of Deus Ex to make it a RPG.
No MMORPGs like Warcraft, Everquest, Guild Wars or Ultima Online? Why do they not fit? Where are older games like Betrayal at Krondor, Pool of Radiance or Icewind Dale?
So nope, I just can't agree. Though every game mentioned on your list and mine were well worth the time to play. On that I hope we can all agree.
