Sure, at least in single player mode. The world is far richer and freedom of action is bejond compare. The only two things one might wish are less resource required technically and bit more glory and tantara at the final of the main quest

The design in NWN is a bit "esthetic", prettier so say. However, there's more of details in Morrowind (there is difference between 3rd and 1st person view after all), and such thing as plug-ins. NWN in SP is far more strightforward, and all those restrictions on areas one can go ... It's built as a book contrary to Morrowind's world to live in and write the book yourself.
The one fundamental thing what was very dear to me in BG was the party and all related to it (all those tactical schemes and strategy and team building, you know, not mentioning care and romances

), what is gone completely in NWN (godess, you can never tell a henchman where to stay and what to do, neither you can direct your familiar without possesion what switches you yourself out, not mentioning the animal companion what cannot be directed at all). IMHO, NWN has notable shifted to Diablo side and so repel or leave disappointed many loyal BG fans.
