Game director of The Legend of Zelda: Tears of the Kingdom, Eiji Aonuma, shared information about the game's development process in an interview with The Washington Post.
It turns out that the game was actually ready by March 2022, but the decision to delay the release was made to ensure that it met Nintendo's high standards and to verify that all project systems, including physics, were working as intended.
Previously, the developers were concerned about the lack of audience interest in the game's February trailer. As a result, they decided to release a special video where Aonuma explained the core principles of the new Zelda game. This helped address the issue.
Additionally, Aonuma mentioned that creating the new game was more challenging for him compared to working on Breath of the Wild. He cited his age and fatigue, as over the past two years, he had played through his creation about 20 times to identify and fix any flaws.
However, the author hopes that the game's creative approach will inspire players both in-game and in real life. Considering the game's overall popularity, with sales surpassing 10 million copies in the first three days, such a outcome is entirely possible.
