Can’t the question of Optionlock or Timelock be answered by asking:
- what drives the action for the story towards the climax?
- what creates the tension?
- why did the consequence occur or why did we believe the consequence would have occurred?
Off the top of my head, I can think of limits that would push a story forward when coupled with consequences (aka stakes):
- a limited amount of time that prevents the application of all options
- a limited amount of time that eliminates certain options
- a limited set of viable options due to imagination
- a limited set of viable options due to intelligence
- a limited set of viable options due to congruency (you can’t have your cake and…)
- a limited set of viable options due to ability
- a limited set of viable options due to opportunity cost
- a limited set of viable options due to consequences
- a limited set of viable options due to practicality
I think that another part of the puzzle that needs to be looked at is consequences or stakes. They are going to arrive if the character doesn’t solve the problem even if there isn’t a set time.
Did they arrive because there wasn’t enough time; because there were no viable options left; because a previous decision caused a limitation in future options; etc.?
It does seem that Optionlock has the most flexibility, whereas Timelock is a one trick pony. Working outside the constraints of Dramatica language, I think a person could call it Optionlimits and come up with a large list of things that limit options including time.
I am not criticizing the language of Dramanta just as I would not criticize Spanish for not having possessives. Different ways of thinking and methodologies bring us to the same destination. Having a specific category for Timelocks is reasonable because it is a common way of driving the action and creating tension or urgency.
As for the original question, are Timelocks always fixed? I think they must be or be perceived to be without the illusion being broken.
For example, if a character tells your protagonist that he will blow up the world in 24 hours unless the protagonist pays a ransom – either the ransom must be paid because the protagonist perceived the consequence to be real or the consequence must occur. If neither of those happen, then it was just an Optionlock in disguise as a Timelock.
I wonder too, if all Timelocks start out as an Optionlock because we have two options always. To believe the Timelock or not to believe the Timelock.
