The instructions for using the Toolset are in your \Program Files\Atari\Neverwinter Nights 2\Documentation directory. This gave the game a very powerful capability which is continued with the use of the Neverwinter Nights 2 Electron Toolset that comes with the game. Just like modules in the old pen-and-paper D&D, you can create entire new worlds and storylines to go with them. The original Neverwinter Nights became extremely popular because it allowed the community to create a range of custom modifications, or more appropriately for the D&D world - Modules. Important: As of the 1.23 Patch, users no longer need to keep the DVD in the drive to play - the disc check component of SecuROM has been removed from the game. Hopefully Atari will listen to the various requests from legitimate purchasers of this game to at least remove the CD/DVD check component of the copy protection in a future patch, as it is annoying and only punishes paying customers. I can however say that SecuROM can cause issues, particularly startup problems - see for details. For legal reasons I can't provide any details of a No-CD or No-DVD, or other methods of bypassing copy protection. Neverwinter Nights 2 requires a CD Key and also uses the SecuROM copy protection system, which requires that the CD/DVD be kept in the drive while playing the game.
