Without a doubt, Baldur's Gate II: Shadows of Amn is the best RPG for any platform in 2000. It even beat out Final Fantasy IX for Playstation - not an easy task. Sporting core AD&D Rules, over 200 hours of gameplay, and hundreds upon hundreds of intricacies and details you probably won't notice the first time around, Baldur's Gate II goes down in my book as the greatest PC game out there right now.
