How many so-so rpgs have there been down the years? That's right, a whole hell of a lot. How many good ones have there been? A decent number, enough to keep me and a lot of people like me playing. How many brilliantly written and brilliantly plotted rpgs have there been, where your moral choices are complex and make a huge difference to not only the outcome of the story, but the whole style of play throughout the 50+ hours of the game itself? How many rpgs let you resolve events in seven or eight different ways rather than just asking you to fight stuff? (though you can do that too) How many rpgs tread into such murky grey areas of personal and ethical hell and do so wilfully and mindfully? Damn few? Yeah, pretty much.
Planescape Torment is not unique. But it stands up there with only two or three other games in the genre for its multi-layered complexity, and intrinsic moral shading. It was, for it's day, a rather pretty game, with it's fascinating setting (the City of Pain) gorgeously gruesome character models and lovely spell effects. It was one the plethora of late 90's rpgs to use the Infinity Engine and of all of them it was the one to create the most beguiling and entrancing world. It had some good, if limited, voice acting and made excellent use of the concurrent AD&D rule set.
Being over a decade since its been released it has certainly started to show its age and even when new it did have some bugs which caused slowdowns and audio failures. Really though these were and are minor issues compared to what the game represented. This was a great, choice filled, crpg experience. And while there have been several games which it can be said to have influenced (Deus Ex, The Witcher, and most recently Dragon Age: Origins) I don't think that any of them are quite as brave and certainly not as original as Torment.
