Via Kotaku, an interview at Evil Avatar about the bad end of the Thief series. They discuss the game series with designer Randy Smith, who details the fine points of the early games and the ignoble end for the trilogy of games. From the article: "I view Thief 3's more action-inclined gameplay as being more than necessary for a mass-market acceptance. The problems with Thief 3 were the same as the problems that plagued Deus Ex: Invisible War - it was the tech. The team scaled back the freeform design, incorporated loading zones, not to mention the unstable frame rate and other misc. issues derived from the technology. The gameplay was relatively solid by comparison."
