Torment: Tides of Numenera - Interview at Dagon's Lair
There's a short interview on InXile's sequel to PST at Dagon's Lair.
Colin McComb is the creative lead, with his experience in world-building and fiction writing as the cornerstone of the story and thematic elements. He worked on both developing the Planescape setting and as a designer on Planescape: Torment. Torment’s project director is Kevin Saunders, who was the lead designer and producer for Mask of the Betrayer, which some of the hardcore RPG fans feel was the game closest to PS:T yet. We have several great concept artists involved, including Nils Hamm, Andree Wallin, Chang Yuan, and Dana Knutson, who was the primary concept artist of the Planescape setting. Mark Morgan is creating the game’s soundtrack – he’s already created a piece for Torment and completely nailed it. A lot of great talent is involved.
