on the other hand it was just a game with exactly the same format as all the other bioware game's such as baldurs gate 1, 2 and expansins, icewind dale and expansion, neverwinternights and the resently knights of the old republic.
Torment and Icewind Dale were done by Black Isle, not Bioware, and apart from the Infinity engine I found them to be very different in style from Bioware's games.
unfortunaly planescape torment had a lot of bugs. becouse of these bug's i have never finished the game. and i think others had those problems too.
With the patch Torment is virtually bug-free and a joy to play.
