Diamond Edition
From NWNWiki
The Diamond Edition of Neverwinter Nights is the latest release of the game. This edition includes the original game (patched to version 1.66), both expansions (Shadows of Undrentide and Hordes of the Underdark), and the three premium modules included in the Kingmaker boxed set, namely Kingmaker, ShadowGuard, and Witch's Wake. These modules are identical to those that can be bought and downloaded from BioWare, but do not require an internet connection to authenticate.
