Unlike many other educational formats, game-based learning can bring fun and enjoyment to the learning experience and might encourage greater participation in group learning activities, with the potential to engage learners’ emotions, as well as their intellects. Therefore, this format could substantially contribute to the development of a wider repertoire of teaching and learning methods in continuing medical education (CME). Although many authors claim that games are as effective as more traditional educational methods, games have rarely been formally evaluated, with positive claims being largely based on anecdotal evidence. Formal evaluations of games, demonstrating that they are actually as effective a teaching and learning strategy for CME as more traditional methods are, are lacking.
