"Scenario games are planning methods to test the viability of prototypes before they are developed by the participants. A scenario game should be the community of a prototype; to sustain this community and its interactions through the game and the life of a prototype is the key to the success of a coevolving plan, a dynamic master plan. Over the years, we developed game rules and started using the four basic processes we formulated after many attempts with role modeling and other characters failed: erasure, origination, transformation and migration as the drivers of the game. The four basic processes create the dynamic substance of the narrative while importing other key processes that form a reality through which a prototype can be tested. Participants are actors through these processes, but become authors once they insert prototypes."
