I was watching an animated episode of Cyanide and Happiness. And there was an episode with a teenager in a theater watching a horror movie. Just when the protagonist is about to open the scary door he screams " don’t go in there" she looks at the audience and says " ok" and heads to her car and leaves smash cut to two hours later and she’s in bed reading and the audience boos as the credits too.
It got me thinking about making a game where you are offered a choice near the beginning. Either you participate in the main plot or you go on a different story with mundane choices and outcomes.
