The collection of interconnected realms featured in the Kingdom Hearts series forms a complex and ever-expanding cosmology. This network facilitates travel and interaction between disparate environments, each typically based on intellectual properties from Disney and Square Enix. As a gameplay mechanic, it structures the narrative progression and exploration elements central to the series’ design.
The interconnected nature of these diverse environments is crucial to the overarching narrative. It allows for character crossovers, the exploration of thematic parallels, and the establishment of a cohesive universe despite the varied origins of its constituent worlds. This interconnectedness provides players with a sense of scale and emphasizes the stakes involved in the conflict against darkness. Historically, the design philosophy behind this structure has evolved, reflecting changes in technology, narrative scope, and player expectations.
