For as long as Persona has existed, its mainline instalments have been exclusive to PlayStation platforms. Sure, we get the offshoot every now and then that makes it to a Nintendo system as well, such as Persona Q or the upcoming Persona 5 Scramble: The Phantom Strikers. But as far as mainline Persona instalments are concerned, they’re only ever available on PlayStation systems (except the first game, which is also on PC).
It’s clear then that the franchise is an important PlayStation mainstay- and it seems Sony feels that way too. At the recent Persona 5 Royal event, Sony spoke about Atlus’ series (via Game Watch), and mentioned that Persona isn’t only a series that is important to Atlus and Sega, but also to Sony and to PlayStation as a platform.
Persona 5 on the PS3 and PS4 was the series’ most major hit worldwide, helping it break out of its relatively niche corner. Recently, it was announced that Persona has collectively sold over 10 million units. Meanwhile, Persona 5: Royal is out exclusively for the PS4 in October in Japan, and in Spring 2020 in the west.
