Koei Tecmo ended 2020 on a high note thanks to Hyrule Warriors: Age of Calamity being a smash-hit for the Japanese company, and several months into 2021 the game has continued to earn more sales. The Musou game--which is already Koei Tecmo's single best-selling game in its genre--has shipped 3.7 million units as of March 31, 2021.

According to the rest of the publisher's end-of-fiscal year financial results, net sales and operating income grew tremendously year-on-year. Atelier Ryza 2: Lost Legends & The Secret Fairy managed to ship over 360,000 copies and the company plans to create a new best-selling IP for consoles and PC. Koei Tecmo's other ambitious goals for the future include creating new smartphone games capable of generating over $9 million in revenue every month, expanding its global business, and eventually becoming the "number one digital entertainment company in the world."

The team-up with Nintendo on the Zelda Musou spin-off has also motivated the publisher to sign more deals with other companies to create similar projects, and it has a five-year development plan in place to create a large game.
