GOG.com is having a sale on D&D games, its a buy 1 get 1 free deal, plus Temple of Elemental Evil for free. Anyone who wants to play the greatest RPG games of all time should jump on this deal. BG1 and BG2 are two of the best conventional RPGs out there, and Planescape: Torment is an amazing RPG, with 800,000 words of dialogue. Neverwinter Nights is good for its multiplayer, seeing as the campaign is lacking. These persistent worlds let up to 64/96 players connect at once to a server. Basically, you can use the game engine to build your own mini MMORPG using the included Aurora toolset.
TL;DR, buy these games
