The Legend of Zelda: Breath of the Wild was a failure for Nintendo when it was in the playtest phase.
Nintendo's developers rarely give interviews or presentations, but the latter happened a few years ago at the Computer Entertainment Developer's Conference in Japan. Unfortunately, the presentation on Breath of the Wild's development was never put online, or translated out of Japanese for a worldwide audience, but now Game Maker's Toolkit on YouTube has successfully pulled new information from that talk, right before The Legend of Zelda: Tears of the Kingdom's launch.
