Game-Based Sprint Retrospectives are a well-used tool in Agile practices as a way to structure Sprint Retrospective meetings. However, this tool has very little scientific proof to back up why Scrum Masters should opt to conduct their retrospectives in game form. While the little research that exists provides proof that Game-Based Sprint Retrospectives help negate common issues with Retrospective meetings, it does not delve deeper into the potential positive effects of the practice. This study aims to start filling this gap by conducting Canonical Action Research with semi-structured interviews and surveys to investigate the effect implementing the Retrospective Game Sailboat has on a game development teams dialogue. The key finding was that the participating team's dialogue did improve over the course of the study as the team went from being quiet and uncertain to being lively and engaging. Possible causes for this change are how the post-it notes provided anonymity, an easier way to formulate team members' thoughts, and an opportunity for equal participation, as well as the game structure encouraging a less serious environment with playfulness.
