Persona 5 Strikers surpasses 2 million units sold
Persona 5 Strikers originally released for Japan in February 2020, followed by an English localized release in February 2021 for PlayStation 4, Nintendo Switch, and PC.
In a newly released financial results presentation [PDF], Sega states that the "Persona 5 series" has surpassed 9 million units. That number presumably includes the 2 million for Persona 5 Strikers, along with sales for the original Persona 5, Persona 5 Royal, Royal's re-releases, and Persona 5 Dancing. Last year, the total sales number for Royal was 3.3 million, for the record.
Of course, the next entry in the "Persona 5 series" is Persona 5 Tactica, set to release in about a week. Atlus recently released a developer diary video for the SRPG.
