/**
 * Base of every world subsystem of The Descent. It exists only in game worlds (play, PIE, -game, the test worlds
 * the automation tests create), never in the editor's own level-editing world: the Python asset scripts and the
 * editor viewport must not grow a sim, a HUD model or a terrain.
 *
 * A subsystem that registers sim steps in Initialize() declares the dependency first, so the sim exists:
 *     Collection.InitializeDependency<UDescentSimSubsystem>();
