Someone trying to be clever about the recent arguments regarding player usurpation of the GM's role as world-creator, the absurd grotesquerie of the 'say yes or roll the dice' rule, and general disdain for both Immersion and setting as anything other than a meaningless backdrop for 'story creation' decided to postulate this supposed 'gotcha' question: "If shared narrative control destroys immersion, then how do kids play pretend together without a GM?"
Answer: Usually EXTREMELY BADLY.
Case in point: my make-believe world of Dark Albion has lasted for coming on 6 years of weekly play.
Little Billy Johnson's make-believe world of "Star War Ninja Turtle Iron Man Avengers of the Galaxy" lasted about ten minutes before his little friends started arguing about how Tommy's Hulk didn't kill Darth Vader because Hulk can't shoot lasers from his hands, no matter how much Tommy says that he can now because he ate more gamma rays while no one else was looking.
Most of the 10 minutes was them remaking scenes from the movies/shows with very limited creativity anyways.
The conflict being unresolvable, they forgot about the game and decided to watch spongebob.
Billy will continue to be dissatisfied by his early collective pretend-world experiences until he discovers the OSR, where he will become a semi-well known blogger talking about a golden age he never actually knew; but will also get to finally play the long and fruitful campaigns in fascinating living worlds like he always wanted to (but had neither the rules nor the right people to do it with) as a kid.
Tommy will eventually discover Storygames and have far fewer friends than Billy, and still won't ever participate in a game that lives past its second session. Almost everyone who knows him online or in person will think Tommy is a massive cunt.
