I agree completely. Skyrim is the game I go to for mindless, beautiful wandering, and it's a very blank canvas story-wise, so it lends itself to being great to mold into your own thing. But NV is a special kind of game imo, since it not only has one of the best stories I've come across in a game, it still gives you all the choice you could want. And with mods, the atmosphere can be as good as skyrim's.
