NWN was great as far as the play mechanics goes. I have all the expansions. What made the game's storyline suck so much ass, as well those of the expansions, was that ONCE AGAIN it was "we must stop the head bad guys to save the world" and the fact of the matter is, you saw so little of the world's that your supposed to be saving personality, you didn't give a flying puck wether the world perished or not.
The Baldur's Gate series kicked so much as not only because it wasn't "Save the world!", but you get to have a huge party of NPCs and the NPCs weren't just cookie-cutter place holder characters, they were practically their ownselves. For crying out loud, if your party members didn't like each other, they might try to kill each other off. Unbelievable.
BTW, who the f*ck is Obsidian and what have they done?
EDIT: And as for the graphics of NWN2, I hope they make it so avatars look like they do in D&D manuals when they wear their armor. =) And don't skimp out on the cloaks! In every PC RPG, developers are always bitching about how hard it is to implement cloaks/capes so they show up on your in game avatar. Bah! Get the problem fixed already and create a method.
