Akeashar: largely due to IFI's 'minimal censorship or no' policy which led to them skipping PS4 after having to censor some artwork in other titles at Sony's insistence.
IFI doesn't have any policy like that.
On the contrary: IFI has censored many things to appease Sony, like Death end Re;Quest 2, and Dragon Star Varnir.
In addition, the only reason why Mary Skelter: Finale was released on PS4 was because IFI had the devs
self-censor and tone down the game as compared to its previous entries, in order to appease Sony's censorship "standards."
In other words, as well as committing explicit acts of censorship of already-made content at Sony's request, IFI is also now telling their devs to draw the artwork for their newer games in a way that will conform to Sony's censorship "standards"
before Sony censors it...hence Sony's censorship regime is wrecking these games to much a larger extent than is usually recognized.
Although maybe it's not
just Sony that IFI is trying to appease with their censorship-abiding ways, but rather, other Puritan type entities as well.
In any case, the point remains that for the most part, IFI disgracefully is a willing and cooperative partner when it comes to censoring its own products.
