Planescape: Torment will always be my favourite game. The writing, the characters, the mood, the music, for me nothing will ever top it.
Calling this a sequel instead of a successor is a bit misleading but whatever. I'm naturally intrigued by what they're doing and will definitely check it out should it see the light of day. It won't be Planescape: Torment. Nothing ever will. But hopefully it will be a well written, immersive game.
I do wonder why WotC are such twits though. It's not like they're doing anything with the setting as far as I know.
