Taking on the role of the Nameless One, a man who does not know who he is, or why he is alive, your job in Planescape: Torment is to find out why out why you cannot die. The game is unique in many ways – death is not the end, and in some cases, it is used as a way of advancing the story forward.
Unlike RPGs released around the same time, Planescape: Torment does not have a primary focus on combat. While there is probably enough fighting to satisfy die-hard AD&D fans, there is a whole lot of roleplaying to do in the game. This is backed up by excellent writing, with vivid descriptions of the NPC's actions, and appearances, all of which could not have been achieved by the graphics of the day.
