To be clear when I say that I never liked NWN 1 and 2 I'm not even talking strictly about the narrative, the characters, writing or what else.
I didn't like them on a mechanical level.
Not a fan of the way they looked ( I found the art in both games butt-ugly), and even less of the way they controlled and played.
EDIT: Also, I remember fiercely disliking the fact that NWN 1 moved away from being a party based game and focused on "Single character plus mercenary".
And to put things into context I'm not talking from a "modern perspective". I was there trying them when they were fresh releases.
Yep, I concur.
That said I did get a ton of mileage out of community made persistent worlds. 3T in particular. In fact I even got involved in its design and growth at one point.
I always liked the concept of what could be done with nwn, more than the implementation itself.
