Tetsuya Nomura said Kingdom Hearts 4 will feature fewer worlds than previous entries in the series [1].

This shift in design marks a departure from the franchise's traditional structure of visiting numerous Disney-themed locations. By reducing the quantity of environments, the development team aims to increase the quality and scale of each individual area [1].

In an interview with Famitsu, Nomura said each world will be larger and more detailed than those seen in earlier games [1]. The decision is intended to facilitate deeper storytelling and provide richer gameplay experiences for players [1]. This approach suggests a move toward more expansive environments that allow for more complex interaction and exploration [2].

Previous titles in the series often balanced a high volume of distinct worlds to showcase a wide array of Disney and Pixar properties [3]. The new strategy indicates that the developers are prioritizing immersion over variety. By focusing on fewer locations, the team can dedicate more resources to the visual fidelity, and mechanical depth of each setting [1].

Nomura said the increased detail is a primary driver for the reduction in the number of worlds [1]. This change reflects a broader trend in modern game design where developers opt for concentrated, high-fidelity environments over a larger number of smaller, more repetitive stages [2].

The transition toward fewer but larger worlds suggests a strategic pivot in the series' design philosophy. By moving away from a 'hub-and-spoke' model of many small environments, Square Enix is likely attempting to align the franchise with contemporary open-world or semi-open-world standards, prioritizing environmental storytelling and player agency over the sheer volume of licensed content.
