SiegeNWN is a utility that allows the user to convert graphics from the game Dungeon Siege into a format recognizeable by Neverwinter Nights. SiegeNWN can be used to create files (.snw extension) that may be legally distributed across the net. With this file it is then possible for another person to create the hak pak necessary to play a module based on SiegeNWN. Basically this means that it is now possible to legally create and distribute modules using Dungeon Siege graphics!
