Scenarios are stories we tell about the future using signals and drivers.
These stories should provoke creative thinking without being crazy stuff. Of course, there can be several plausible scenarios.
Also try to give a feeling how it is to be a person in that future scenario.
Underlying story archetypes are growth (extrapolation without disruption), constraint (society imposes constraints, like we see during the pandemic), collapse (breakdown) and transformation (fundamental reorganization).
This is an example of future scenarios and story-telling. It can also be considered as a card game, since in fedwiki the signals are cards.
