Again and again, Jaron reported back details in the world that he, the god, had not foreseen. Simulations are not new. Nor is visiting them.

Certainly the urge to create toys arises very early in individual development.
Children immerse themselves in their own artificial worlds of miniatures.
Dolls and choo-choo trains properly belong to the microcosms of simulation. We've come from inert figurines to SimCity. Some simulations, like Disneyland, are no longer so tiny. Anything at all, in fact, is a candidate for a simulation when it is given energy, possible behaviors, and room to grow. We live in a culture that is rapidly animating a million objects into simulations by electrifying them with smartness.
