Gameplay. This is where Neverwinter Nights: Hordes of the Underdark really shines. Ever since the first NWN, people have wanted to venture forth into the dreaded Underdark and face the perils that dwell there. They have also wanted the experience cap lifted as well as epic levels and more material for the NWN toolset. Bioware has delivered in spades adding a new three chapter campaign, epic levels, six new classes, more monsters, new characters and an experience that is reminiscent of Baldur's Gate II. The only real problem with the game is that I wish it were longer.
