Hated NWN, thought it was crap. It looked and played like a PS2 game, the campaign sucked (I never actually finished it, it was so bad... 'solve the mystery of the plague'. Screw that, unless you give me a REASON to solve it (AKA Sarevok kills your foster father, you wake in a mysterious jail with experiments being performed on you in BG1 and BG2), it's just lowgrade cliche. In BG1 and BG2 I WANTED to finish the story. In NWN I was apalled that they actually thought they could sucker me with such a weak plot, realistically I'd rather have just left the damn city.
Plus I hated the third edition rules. Let's give everyone some form of another class's skills! Yeah!
