In this paper, we describe a multi-site evaluation of SimSE, an educational software engineering simulation game. This study was designed to build on our previous experience of evaluating SimSE in courses and controlled lab settings at UC Irvine, in order to validate our findings and discover any factors that come into play when SimSE is used in other institutions. The study consisted of three different universities using SimSE in their respective courses and reporting the results to us. The results confirmed several of our previous findings, as well as highlighted a number of critical considerations that must be taken into account when using SimSE in a course.
