Direct download retailer GOG.com has put the Diamond Edition of Neverwinter Nights up for sale on their site. Neverwinter Nights: Diamond Edition contains the original Neverwinter Nights and all three of its expansion packs: Shadow of Undrentide, Hordes of the Underdark, and Kingmaker. The game costs $9.99 to download, and can be found here.
In order to promote the release of Neverwinter Nights on their site, the staff of GOG.com are teaming up with Neverwinter Nights fansites to hold a pair of contests. The first contest requires fans to create a module for Neverwinter Nights titled "The Tale of the DRM Monster and the Treasure of GOG." The second contest asks fans to create a model and animations for a "DRM Monster" for use in the game. GOG.com is offering free game downloads from their site as prizes, and the contest will run until November 24. More details can be found at this link.
