During the fifth Rendez-vous de l'Histoire in Blois, from October 7 to 11, 2026, eight history and geography teachers will take part in a unique challenge: creating a video game in 48 hours. Each teacher will select a topic from the high school curriculum and work with video game specialists to transform it into an interactive experience. This year, the teachers are central to the creative process, guiding the development to ensure both historical accuracy and educational value. A "game jam" is a competitive event where participants create a video game within a short timeframe, often over a weekend. The Rendez-vous de l'Histoire Game Jam is co-organized by Clionautes and La Science entre en jeu. Following an online meeting on September 23, the eight teams will have the weekend of September 25 to 27 to design and build their historical games. Each team includes a teacher, a game designer, two programmers, two artists, and a sound specialist, working under tight time constraints to develop a coherent and playable game. William Brou, president of Clionautes, highlights the importance of thoughtful design in these games. Simply transferring a lesson to a screen is not enough; the game must engage players in meaningful ways, allowing them to explore historical situations through actions and decisions. The collaboration between teachers and game developers is crucial in defining the learning outcomes and ensuring the game aligns with educational goals. The teacher’s role is to guide the process, ensuring historical accuracy and that the game meets the desired learning objectives. Past experiences show that some games created during the jam continue to evolve after the event. For instance, Ex Decreto, developed during the 2022 Game Jam, was further refined and expanded after the initial 48-hour period. This raises an important question for teachers: how can a game remain relevant and useful in the classroom beyond its initial creation? The public can watch the entire process on YouTube Histoire en jeux and Twitch, from the initial concept to the first tests of the games. These games will be showcased in Blois during the Rendez-vous de l'Histoire. The Game Jam will take place entirely online through the WorkAdventure platform, allowing teachers who cannot attend the event in person to participate live. For the participating teachers, the challenge is twofold: to create a game that is engaging and enjoyable, and to design a scenario that encourages people to learn and appreciate history.
