Rather than letting one person read the book like most audiobooks, we have several fans reading each character and we insert sound effects (ex.a tiger's roar) throughout the sound play.
For example, let's use The Invasion. Guy #1 can play Jake and say "My name is Jake..." blah, blah, blah. But rather than Guy #1 reading the part of Marco and Rachel and whatever, we get different voices for them whenever they have any dialouge. The narration and Jake's dialouge only has to be done by Guy #1. And we get occassional sound effects like hearing Jake's dog Homer barking and Tobias' cat Dude meowing.
