Which Fire Emblem mobile game surpassed $1 billion in earnings in 2022?

Fire Emblem Heroes surpassed $1 billion in earnings in 2022.

Released for iOS and Android in February 2017, Fire Emblem Heroes is a free-to-play strategy role-playing game built around collecting and upgrading heroes from across the series. Its ongoing revenue came largely from in-game purchases, including Orbs used to summon characters from rotating banners.

The game became Nintendo's first mobile title reported to pass the $1 billion mark. Before reaching that milestone, it had generated nearly $300 million during its first year and had grossed more than $959 million by 2022 in reported estimates. Japan accounted for more than half of its revenue, reflecting the game's especially strong performance in its home market.

Fire Emblem Cipher was a physical trading-card game, Fire Emblem Warriors was a console action spin-off, and Fire Emblem Engage is a separate 2023 strategy game. None of those titles fits the mobile-earnings clue. Heroes also became the most financially successful game in the Fire Emblem franchise, despite not being a traditional numbered mainline entry.
