Thanks! We loved making the game, especially as we realized at the time that we'd probably never have another opportunity to make something like it again. We were a great team, we all understood exactly what we wanted, and Chris provided a wonderful base of fiction to work everything else around.
Sorry, no sequel ever I'm afraid, for reasons mostly business-related and partly personal. While Torment made more cash than most people gave it credit, it wasn't near what Icewind or of course BG brought in.
I might be wrong about this (I don't work there anymore,) but I'm of the understanding that Interplay can't even sell anything Planescape-related anymore as the result of some of their WOTC fallouts.
On the personal side of things, I don't think any of us ever wanted to do another Torment, especially as the content was geared towards getting that story out in one shot. Even in a perfect world where we'd do another, we wouldn't have continued the story of the Nameless One because it was done. I suppose we could have hacked something together involving him serving out his contract in the Blood War, but I think that would have been pretty artificial and besides the point; he already had his answers.
