For me, NWN was a failure, even though 3E DnD rules on their own have flaws, NWN just made the mess even bigger. Since I rarely play online as well, I lack even more of the fun that one could possibly have. The conversation system and menu system are just utterly boring to me and overall the rules system used in NWN (which really isn't 3e DnD anymore) is kinda crappy imho.
Of course, I'm glad for people like this game, but it's just not my cup of tea. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
