The game TerriStories comes with four game boards, allowing to represent the fitting of social and spatial logics. In the use, it helps participants to establish a diagnosis and recommendations which involve actors’ dynamics at diverse socio-territorial scales. For the moment, the game is used in the South around questions in management of natural resources, territorial economic development, on a local scale but more and more on a national scale (dialogue for a land reform). The simulation forces the operating of each rule, the participants agree on rules which are at the same time endogenous and operational in a single workshop.
