NWN2 is actually pretty fun with the expansions. I wasn't expecting much in the way of plot but it pleasantly surprised me a couple times. It got a little tedious in the underdark and I don't think I ever finished it but I probably will one of these days.
Storm of Zehir is cool for being party based IMO. I'm not sure how they managed this, but the camera was less annoying in NWN 1 then NWN 2.
Rickenbacker, I have tried NWN2. My outdated PC can run it with a reduced level of detail. Single Core AMD @ 2.4Ghz 2GB Ram AGP X1650 PRO Windows XP I think most of the technical issues have been resolved. Actual gameplay may or may not meet your expectations. If you shop ebay / amazon, you can get it cheaper than normal retail. Dig
