NWN might not have the marvelous tactical combat interface that ToEE has, but it does have humor, interaction with npc's, and actual stories that are both fun to learn about, and interesting. HotU has gone gold, and a 12-2 release date has been announced.
HotU is an expansion for Neverwinter Nights, from Bioware. It's not a PARTY type RPG; you only have one player character, and are forced to bring along hirelings in order to win the combat scenes. HotU is the acronym for "Hordes of the Underdark", and focuses on fighting the Drow, Duergar, and other dwellers in darkness from the FR fantasy world environment.
