Whereas the majority of empirical studies in the field of simulation and gaming are based on one specific simulation game, this study includes a broad range of mostly business-related simulation games. Looking across the border of a single simulation game this article analysis, what are general aspects of simulation games that have an impact on the success of simulation game courses. To do this, we evaluated courses that were taught with 33 different simulation games and collected feedback from more than 3,100 participants. On the one hand, the study shows good values for the comprehensibility of simulation games, on the other hand, the practical relevance is rated lower. As both aspects are crucial for the success of simulation game courses, more emphasis should especially be given to illustrate the practical relevance of simulation games. In addition, the study shows, that there are several significant differences between computer-based and haptic simulation games. Nevertheless, the differences are of no practical importance with respect to satisfaction and learning. The study also shows that, overall, the difficulty of the simulation games and the way in which they are facilitated is appropriate for the participants: While the difficulty is exactly right for about 80% of the participants, it is rather too low or too high for about 10% of the participants.
