““...the video-game form is incompatible with traditional concepts of narrative progression. Stories are about time passing and narrative progression. Games are about challenge, which frustrates the passing of time and impedes narrative progression. The story force wants to go forward and the "friction force" of challenge tries to hold story back. This is the conflict at the heart of the narrative game, one that game designers have thus far imperfectly addressed by making story the reward of a successfully met challenge.””
