The document proposes a storytelling model for educational games. It discusses using an interactive storytelling approach and outlines a software architecture and structure for interactive storytelling games. This includes dividing the story into stages based on Joseph Campbell's hero's journey model and extending this model to account for player interactivity and adaptability. Examples are provided of how this approach could be applied to educational games.

6. IS and game septembre 08 STEG 2008 Final Fantasy series: - Elaborated scenario - no control of the narrative The Sims: - Complete freedom - No scenario but a succession of independent events.

7. Scenario oriented The game is based on a prewritten scenario. The game monitors player’s behaviour and prevents him from breaking storyline. septembre 08 STEG 2008

8. Emergent narrative No story written, but a game full of autonomous agents (characters). The story emerges from a sequence of interaction between the player and agents. septembre 08 STEG 2008
