"Words that change the world" is a long form. At the beginning the audience can be asked for a place where the story begins. The audience will also be asked for a sentence that will appear in the scene. The opening scene will be repeated again and again later, so it is important to pay attention to how and what is played. It is therefore helpful not to talk so much, but rather to act. During the first run you start in the starting scene, at some point the sentence in question comes, but the story continues to be played. When you realize that the story has reached a point where you can interrupt, so one beat comes to an end, you can stop the story and start again in the opening scene. You choose the same scene setup with the same players again. It is best to repeat the first scene starting three or four movements in front of the audience's interrogated sentence.
After this sentence has been dropped, the story will develop differently. That is why this form is also called "words that change the world". Motivation for this new narrative thread may be a changed emotional reaction to the sentence, or the sentence may be perceived and interpreted differently by its recipients. In any case, the sentence in question is the turning point at which everything changes.
Almost everything, because the facts set in the first story are still valid in the second and all subsequent stories. If, for example, in the first scene Player A has a mother (Player B) and she has the name "Marie", this is also the case in all following stories. If player A is as poor as a church mouse in the first scene, this can change in the progress of the second story (because he wins the lottery, makes an inheritance, etc). In the third story this begins poor again. Maybe he buys himself another lottery ticket in this scene, but for some reason it is his turn later and therefore he does not draw the winning lottery but a blank, but the customer before him wins the money (because the fact that there is a winning lottery ticket could be taken up again here). You can tell several stories, each with a common starting point, each with a different focus (the hero of the story can always be someone else), but still connected by the facts. It is even the case that facts in later narratives can change interpretations of previous stories. So one should also have this circumstance in mind.
This kind of narrative play reminds a little of films like "Groundhog Day", also here the starting sequence is assumed to be always the same, but the hero changes in the course of the story, because he himself knows about the previous stories and influences them. That is not the case with this long form.
