As opposed to make-believe (''why?''), interactive non-fiction is the interaction of real-people through an intermediary about real-issues, real-decisions, and reality. This wiki is an example of InteractiveNonfiction. Here, we discuss and debate, conduct dialogue and open for examination and review our thoughts, ideas and knowledge. 

''So basically, like LiveActionRolePlaying only if you die in the game you die for real?''
