Australian Classification Board and USK both show that Fire Emblem Engage's production was wrapped up back in 2021

We recently learned that the codename for Fire Emblem Three Houses was ‘Iron17’ and ‘Iron19’ for Fire Emblem Engage, which led to speculation that there is another Fire Emblem game that exists between Engage and Three Houses. The speculations have now only gone wilder as we also just learned that both the Australian Classification Board and the USK in Germany show that Fire Emblem Engage’s production was wrapped up sometime in 2021, meaning there was at least a one-year gap between the game finishing production and its release. Some speculate that the other game could be the rumored remake of Fire Emblem Genealogy, or it could just be a project that was canceled. Only time will tell.
