I find it easier to try to make sure I understand before just continuing with an exploration. Seems harder for people to follow when I don't ask for clarification. Patience is very easy online.
1) I think not. If the requirement and the consequence are the same, then you are reaching the goal and not reaching the goal at the same time. This is a structural consideration. Requirement Type represents what is necessary to achieve the goal and Consequence Type represents what happens if the goal is not achieved. If these two things are illustrated the same, what will that look like to the audience?
2) So, you are trying to apply Dramatica Theory to a story you already have written? Do you have Dramatica Pro 4 or Story Expert for Mac?
3) There are 4 Throughlines. Each Throughline is explored through one Class/Domain each. When each domain is explored during the story timeline, each Type is explored in a particular order (depending on choices you make) and all 16 Types are explored in the Grand Argument Story. (Again, seeing it in Dramatica Pro 4 or Story Expert for Mac helps a lot).
4) Dramatica calls complete stories, Grand Argument Stories and generally everything else is called a Tale. I think some movies and such can have goals without very strong consequences or costs and rewards along the way, but none that I can think of as "successful." Do you have an example of a story without a clearly defined goal that inspired you or are you having trouble clearly defining the goal in your own story?
Happy New Year.
P.S. I am just thinking with you, I am not an Expert here, so thank you for your patience too.
