One of the all-time greatest games of ANY genre...
A great storyline, wonderful characters, interesting side quests and beautiful graphics make this a near perfect game. The game's use of the Baldur's Gate engine and isometric view gives it an atmosphere that is unique, yet familiar. The interface takes some getting used to, but the auto-pause feature mostly offsets this, preventing the UI's kludginess from seriously detracting from gameplay.
What really makes this game stand out is the story. The story is one of the most immersive I've experienced since the days of text adventures (when the story WAS the game). With the recent shortage of good scripts in Hollywood , I would not be surprised to see an adaptation of this game on the big screen some day (anything is better than another Beverly Hillbillies movie).
When judged within the context of the year of its release, this game has no real weaknesses, although fans of gratuitous cut-scenes may be slightly disappointed. Planescape: Torment requires players to read and use their imaginations more than most modern RPGs, but is that really a negative?
