Following their retrospective review of Baldur's Gate, the editors at Mana Pool have turned their attention to Planescape: Torment and awarded it a 9.6/10. The only game capable of knocking Ultima VII out of its lofty orbit, this one is:
Once again, Planescape: Torment suffers from similar problems to reviewing Baldur's Gate due to the age of the graphics, and due to it not being a standard of games of the time that all dialogue be voice-acted. Also like Baldur's Gate, the graphics are primarily high quality 2D graphics, and so it is not that noticeable once you are used to it, and the voice-acting and music are of very high quality, rendering a lack of total voice-acting less problematic than it might otherwise be. The lack of voice acting isn't an issue for me (and, I suspect, many of you) and The Gibberlings 3's widescreen mod bumps the game's graphics up to nothing short of stellar. If you haven't played it, get it, now.
Unlike Baldur's Gate, the game has a very particular and slightly weird style, as befitting the weirdness of the world itself, and thus the game's age is probably even less of a hindrance, as you probably won't have played anything quite like it anyway.
The music in particular has a haunting quality to it, and really adds to the immersion within the game.
