Here´s the article´s intro:

Neverwinter Nights is a Third Edition Dungeons and Dragons computer roleplaying game. The emphasis is on multiplayer play with one player serving as a Dungeonmaster (DM), although it supports solo play and multiplayer without a DM as well. It uses the Omen engine first developed for MDK2, with an isometric view supported. The game will ship with 28-30 modules that are linked adventures that can be played alone or online. It will also feature a robust editor that Bioware promises will be easy to use for players who want to make their own adventures and share them online or DM them. There will be no fee to play online with up to 64 players in a game at once...
