If it had been announced and marketed as this, you might be right. But it wasn't. It was marketed as a Single Player RPG.
But aside of this:
If NWN isn't a Single-Player PPG, it is not relevant for the discussion at hand, which was about the Bioware direction with respect to Single-Player RPGs.
So I concede all your points but stay by my original description (which was a sarcastic hyperbole anyway).
