Narratives are used to construct and deconstruct the time and space of events. In games, as in real life, narratives add layers of meaning and engage players by enhancing or clarifying content. From an educational perspective, narratives are a semiotic conduit for evoking critical thinking skills and promoting knowledge discovery/acquisition. While narrative is central to Serious Games (SG), the relationships between gameplay, narrative and pedagogy in SG design remain unclear, and narrative’s elemental influence on learning outcomes is not fully understood yet. This paper presents a purpose-processing methodology that aims to support the mapping of SG design patterns and pedagogical practices, allowing designers to create more meaningful SGs. In the case of narrative, the intention is to establish whether Narrative Serious Game Mechanics (NSGM) can provide players with opportunities for reasoning and reflective analysis that may even transcend the game-based learning environment.
