Basically, this is a game where a player makes a wish and it gets ruined, like in the story about the monkey's paw. For example, the first player makes a wish that Naruto would continue. Then the second player could do something like "Naruto continues for several more years, but it's full of subliminal programming telling everyone to obey the new world dictator." Then the second player makes a wish of his or her own, and so it continues.
I wish i had a stick.
