Simulation Theory
What if the world has a substrate, and someone finds the seam. Simulation stories put reality itself under audit, a glitch, an anomaly, a level of resolution that fails under close inspection, and their gravity comes from being the one premise the reader cannot fully rule out on the way to work.
The premise's bill, at this desk, is not the metaphysics but the morning after: granted the discovery, what changes about a life, a duty, a love, and the strong versions answer with humility, finding that the substrate question, however it resolves, leaves the human ledger intact, appointments still kept, people still missed. That finding is the subgenre's quiet consensus and its maturity. Craft turns on the evidence: the seam must be earned, specific, and resistant to easy testing, because a world too obviously fake forfeits the vertigo. The failure mode is revelation as ending, the curtain pulled and the story stopped, as though discovering the stage answered anything about the play.
