Serious games have several advantages for learning over more traditional activities. One of those advantages is that being highly interactive, they provide a firsthand simulated experience to the users. Serious games can also generate interaction data that can be used to assess learning, both for evaluation and to provide timely feedback for learners or even adapt aspects of the game on the fly. However, this potential is currently far from realized because doing so requires significant investment and expertise as compared to more traditional educational activities. Additionally, game learning analytics continue to be a costly and fragile process. We propose a combination of tools that greatly reduces the associated costs of building serious games with meaningful analytics simplifying the validation of those games and their deployment in real settings. We consider that this can be a key step to building predictive assessment avoiding the need for disruptive external assessment thus bootstrapping serious games to recognize learning through analytics.
