Planescape: Torment is a 1999 role-playing video game developed by Black Isle Studios and published by Interplay Entertainment for Windows. The game takes place in locations from the multiverse of Planescape, a Dungeons & Dragons (D&D) fantasy campaign setting. The game's engine is a modified version of the Infinity Engine, which was used for BioWare's Baldur's Gate, a previous D&D game set in the Forgotten Realms.

A role-playing video game, a role-playing game (RPG) or computer role-playing game (CRPG), is a video game genre where the player controls the actions of a character immersed in some well-defined world, usually involving some form of character development by way of recording statistics. Many role-playing video games have origins in tabletop role-playing games and use much of the same terminology, settings, and game mechanics. Other major similarities with pen-and-paper games include developed story-telling and narrative elements, player character development, complexity, as well as replay value and immersion. The electronic medium removes the necessity for a gamemaster and increases combat resolution speed. RPGs have evolved from simple text-based console-window games into visually rich 3D experiences.
