It seems like a lot of people passed up this one; the first Neverwinter Nights had a lot of potential, but was a game for people who like mods and module building. This game has all that flexibility, plus three of the best D&D campaigns that have ever been adapted to PC. The original campaign is equal parts lighthearted parody of classic D&D cliché and clever subversion of the tropes of the standard campaign; it's full of little jokes for people who know the system, but it's also a rich and fun story for anyone who doesn't. Storm of Zehir is the closest thing I've ever encountered to actually playing pen and paper D&D - it's a genuine campaign, full of asinine player choice, freedom and scope. Both are excellent D&D campaigns. Mask of the Betrayer is basically the harrowing dreamlike lovechild of Baldur's Gate II and Planescape: Torment. And it's an Epic campaign, so is suitably ridiculous to boot.
