Prov-DIFF: Play traces analysis through provenance differences

A game session comprises a series of user decisions, inputs, and the execution of a strategy to reach specific goals. Tracking generated data of a game session is important for game analytics for developers and players. Game session data can be used for reproducibility, analysis of game traces, understanding player behavior, and improving the outcome in future sessions by learning from mistakes. However, game telemetry can rapidly lead to large amounts of data that can overwhelm the analyst’s ability to analyze it, and it can be difficult to identify the reasons that might have caused a player to lose in that session. This paper proposes a provenance-based automatic debugging approach for game analytics. It identifies possible reasons and discrepancies that might have led a player to lose by contrasting their performance with other players. Our approach also proposes possible insights on how to improve the player’s performance to reach the goal. We integrated our solution into the existing provenance visualization tool Prov Viewer. We provided an experimental study to demonstrate that our approach can identify probable causes that led the player to lose and propose changes to make it work in the next execution.
