The Blood Moon in Zelda is a perfect example of harmony between engineering and design. It's essentially a cache busting mechanism that NEEDS to happen to conserve system resources. Instead of trying to make it something "the user doesn't notice" by trying to hide it from them, they interwove it into the story, the experience, and the lore. It actually has consequence for the player, which is SO much more interesting. They took a technical limitation and flipped it upside down. This is how you can tell their engineers were designers, and their designers were engineers. It's a cohesive unified vision for the product that perfectly balances design with technical excellence. Even if the hardware was 10x more powerful we'd still want the Blood Moon.
