Building upon research on motivation theory, we provide insights on how video games can be framed as expert tools that naturally reconcile learning and fun, a worthy goal since students are forced to where players volunteer, namely learning. Our main contribution is to suggest best practices rooted in psychology and motivation theory that we believe should be used when designing educational games. As a case study, we illustrate this approach by looking at the design of our ongoing Cha-Luva Swing Festival project, a video game dedicated to music education. Its overall pedagogical goal is to spur the players’ curiosity and creativity by enabling them to easily play music using gamepads as musical instruments. This example perfectly illustrates our results, since motivational lapses due to instrumental limitations often lead to resignation and surrender.
