A transition towards a safer, healthier, more equitable and more sustainable world requires focused Sustainable Development education. While this is true for all forms of education, it is particularly vital for business education curricula, and here it is sorely lacking. The main problem is that teachers lack the methods to teach sustainability competences. Gaming is proposed as a suitable method, as it involves action, direct feedback and high motivation. In this research we used a pre-post tests research set up to measure the learning effects from three simulation games. These games were played with 160 2nd year business students. We conclude that simulation games have limited contribution to cognitive learning about SD. However, a majority of respondents see additional value of gaming within their education.
