The long and juicy Fire Emblem license has multiplied titles since 1990, with 16 games available and never more than 3 years between two titles. The latest games have helped make the license all the more popular, especially FE3H on Nintendo Switch which has been a great success despite its few flaws. The studio that created the license, Intelligent Systems, has been quiet for the past few years. It seems that his investment in the development of FE3H was minimal, with the bulk of the workload left to Koei Techmo Games. Now, the dubious remake of Advance Wars 1+2 (another of its major licenses at the time) is being made by another studio.
We'll have to keep waiting for a real Fire Emblem. You could say the Nintendo Direct played with our emotions by announcing a new Fire Emblem, then sticking "Warriors" next to it. It's not a real episode of the license, but one more Musou in order to easily make the license profitable, as was the case with Zelda Breath of the Wild which was entitled to a few years for example with Hyrule Warriors.
Titled Fire Emblem Warriors: Three Hopes , it picks up the Three Houses universe and characters, but with a new story. The release is relatively close, since it is scheduled for Nintendo Switch on June 24, 2022 .
