In the far, far, future, a middle-aged father has fallen behind the times. Bemused and disturbed, he watches his children play the eponymous Game of the Worlds, a Total Reality war game that involves the annihilation of countless alien civilizations--which are at least as real as the narrator's own. As he debates the ethics of the game, struggles with his home's "intelligent system," and fumblingly manipulates his Discourse Corrector (a dead ringer for ChatGPT) on virtual beachside dates, an errant thought threatens to set a world-ending chain of logic into motion: the return of the Idea of God... Epic and domestic, madcap and musing by turns, this prescient novel reads like a message in a bottle from a bewitchingly strange yet all-too familiar future.
