Quantic Dream have released the full 12 minute The Dark Sorcerer tech demo. they teased this during the PlayStation 4 segment of Sony's E3 press conference. David Cage reveals the idea behind The Dark Sorcerer was to create a tech demo that explored comedy. this requires good pacing, talent and good story, but the big hurdle is cultural differences as to what is funny. he also used the demo to create a face that's not quite human to try to adapt their Motion Capture technology. The Dark Sorcerer stars David Gant as the Sorcerer, Carly Payne as Maurice, Christian Eriksen as a Demo and David Gasman as the director.
