Abstract
Producing educational serious games can be costly and time-consuming. The Service-Oriented Architecture (SOA) approach of software development can offer a solution to reduce costs and foment serious games development. In this work, we apply a model called Activity Theory-based Model of Serious Games (ATMSG) for identifying existing relevant components that can be reused for different educational serious games. We apply the derived structure to classify the elements of an existing game and to identify how it can be refactored and expanded following the SOA paradigm.
