This plugin just "select" a possible story from some possibilities and requirements, the only thing it does is to give you back the variable "Hey, based on your preferences, I've select story 5" that's it :)
Playing the story 5 is up to you when variable X has the value 5
It is a sorter, you put stuff in it with a bunch of rules, percenage and chain-links and he does the sorting but doesn't actually show any event
