Torment is world's better than BG2 and still the best story and dialogue ever put to an rpg. Console or PC.
I found it to be quite a bit worse than BG2 and many other RPG's including DA:O. Good you like it, though.
Weren't they trying to remake Planescape at some point? I wonder how that is going or if they stopped the remake, or maybe I'm confusing it with a different game remake. I'd love to see HD remakes of all the classic RPG games if they are done properly. Like, keep the same gameplay/story/quests, but upgrade the graphics to HD so that it looks more crisp and that it supports new monitors/resolutions without issue, and fix some bugs that are in them and make the menus more clear/updated.
