There have been countless games that have been loosely based or strongly influenced by the medieval world of Dungeons & Dragons but there are only a handful that adhere to the rules governed by the official D&D and Forgotten Realms ruleset. Neverwinter Nights 2 is one of these games and perhaps this fact alone makes it more appealing than your average RPG. Now that NeverWinter Nights 2 is available on the Mac OS, everyone on Mac and/or PC can play.
