My opinion on NWN is that it didnt age as well as BG simply because of the 3D graphics.
No argument here from me. Whatever "custom content" benefits NWN1/2 engines had, I felt they were poorly suited for crafting compelling main campaigns.
Still, campaign itself is solid. Reasonably well paced, and while story isn't terribly exciting, companions are enjoyable and it had some really creative and influencial bits. MotB expansion is just good.
