Interactive storytelling

• Interactive storytelling is a form of computer entertainment in which players take on the role of a protagonist in a dramatic storyline. The term was coined by Chris Crawford, a main proponent and developer.

• Interactive storytelling and interactive fiction are distinct in that interactive storytelling focuses on drama and dynamic circumstances, whereas in-teractive fiction traditionally (but not necessarily) focuses on puzzle-solving and navigating through pre-conceived circumstances. Well-written exam-ples of both should be nonlinear.
