Lol, i agree there, NWN's single player campaign was horrible. Heck even the "hardcore" NWN fans will probably tell you they never finished it.
I actually know one of them. He's a long-time member of the community there. He bought the english version *very* soon, and told me he was highly disappointed.
I haven't seen him for a while, that's why I even can't remember his name. The only thing I remeber is that he represents an Dark Elf in the community.
