They rarely respect the creative component of actually playing music. In this publication, a novel improvisation game-play element is introduced to account for the creativity. An evaluation is conducted to assess, whether improvising music as a game-play element in music games can increase the entertainment factor. Therefore, prototypes of two improvisation-based music games are implemented and compared to a simple rhythm game with regard to the entertainment factor. The evaluation shows that the entertainment factor can be significantly increased by an additional improvisation part in rhythm games. A purely improvisational game instead does not significantly improve the entertainment factor compared to a purely rhythm-based video game.en621conference paper
