Was thinking we could have mad libs..Not creative myself to make a backstory, but here's one possibility.. One person has a list 1 to 10, with each number asking for noun, verb, adjective, etc..everyone chimes in..then when it's agreed upon, then original poster pulls story..then another agreed upon person or person who has story can ask for another..Not sure of how it'll work in this context, since it's online game and not in person, but should be similar..

Essentially someone can create a short story, leave out certain words and ask for certain words from others; then make the story with wacky words...
