Regarding the performance, I tried the demo on PS5 and it ran pretty well. I haven't finished it yet but got about ~2 hours in and liked it a lot. The whole "monsters are called 'humans'" thing was a bit on the nose but I don't mind that much. There's something about the art style of the game that I can't quite describe; it almost feels like a watercolor painting but also cel-shaded? Either way it's unique and the UI is pretty striking as well.
Like you I will shovel into my mouth whatever Persona/SMT slop they give me so I'll probably get it when it comes out.
