In this paper, we describe the design and implementation of a game called STORYFIGHTER that uses a system of causal reasoning and common sense database knowledge. The story has a predetermined start state and goal state, and the objective of the user is to alternate telling sentences with STORYFIGHTER to arrive at the goal state within a limited number of steps.An example interaction could be a start state of "John is sleepy", and a goal state of "John is in prison." STORYFIGHTER uses a semantic net of causal predicates to generate response sentences to user inputs. If there are no inferences that can be deduced, then STORYFIGHTER queries the Open Mind Common Sense Database for related common sense data sentences.
