Jjodel for Serious Games: A Metamodel-Driven Vision for Assisted Game Design

Serious games are a powerful way to explore complex problems and promote critical thinking and decision-making in uncertainty. However, designing such games remains a challenge, particularly when integrating real data, modeling domain complexity, and aligning gameplay with learning outcomes. This paper introduces a framework designed to support the structured co-creation of serious games. The co-design process is structured around a formal foundation of interconnected metamodels, each capturing a key dimension of serious game design, such as threats, actors, functional roles, territorial contexts, and event dynamics. These are grouped within a central Megamodel to ensure coherence and traceability throughout the scenario. Although not all aspects are fully implemented, this work lays the groundwork for an assisted design vision, in which AI tools support designers through model validation, reuse of game components, and guided content generation. We outline how the framework, instantiated through the Jjodel platform, can be used to rapidly prototype new game scenarios by adapting and extending a reference game structure across different domains.
