In making a multiform story, whether on the Web or using a procedural environment like Character Maker, we can easily find ourselves overwhelmed by the possible directions the story could take.
It is important to approach these possibilities in an organized manner.
Even if you think you know all the combinations, it is helpful to methodically examine them. The interactor may expect combinations that you have overlooked. You may also want to reconsider which one you have included and which you have excluded.
Here are some sample tables that demonstrate the magnitude of possibilities that can arise from relatively few choices.
For choice of two elements out of five (assuming you can't choose the same element twice):


































For choice of two out of n elements, result is (number of items1) + (n2) + (n3)….[until nn]
2 selections out of 5 elements yields 4+3+2+1=10 possibilities
But the generic formula is more complex. Where K= the number of items chosen, and N= the number of items in the complete set, the number of possible choices is calculated like this:
___________
((NK)!) (K!)
For the example above that would yield 5x4x3x2x1 =120 divided by
(3x2)(2) = 12
120/12 = 10
