We plan to extend Play tracer in two additional ways. First, we hope to aid in the exploration of temporal patterns that are embedded in play data. For example, a game designer may want to observe patterns in the times at which players reach a particular state in the game. Our current system is primarily intended for viewing spatial relationships between game states and is unable to support visualization for temporal queries. This could be accomplished by adding a third dimension to the display and is an area of future work. Second, we believe that Play tracer could be useful for evaluating prototypes in iterative game design and refinement. We hope to explore the potential for using our tool to identify a weak point, fix the component, redeploy the game, and then show clearly that the weakness has been removed.
