Shared game data can serve as a critical input to the development and testing of new research tools. In this interview with Luke Swanson and Zhaoqing (Jimmy) Teng, we explore how progression visualization can be used in learning games research, particularly when games have a non-linear structure. Using the shared gameplay data, Jimmy was able to iterate through versions of the tool, and refine the analysis and user interface.  “You can select a specific action and understand, for example, how a player reached this action,” he said.
