To improve retention rate of factual knowledge for health students we set out to design a game which challenges students to continue testing themselves during their studies. Since we intend for them to play this game for at least two years, we had two major challenges to overcome. Firstly, how can students feel motivated to continue playing for two years on end, and secondly, how can enough content be generated for a two-year game play. The first challenge was solved by tapping into a core motivation of health students: many intend to start their own practice and for that, they want to be involved with other practitioners. We, therefore, proposed a sim-type game in which students cannot just practice on virtual patients but also on practitioners logged in as a patient. The second challenge was tackled by building a flexible framework for case collection, and including the production of those cases in the curricula of the involved programmes.
