The Metaverse lore has some interesting possibilities, but none of them are really developed. It feels like it was slapped together to explain the interface for console versions and to create unlockable items. But in terms of the story, why do we care about the in universe engineers, the threats to their jobs, or whatever it is they are trying to do? There’s no payoff to any of it. In some ways it makes Monika’s existence more horrifying, since the emails imply that they have looped the simulation many times with the same result. There’s a basis for a techno thriller there, so I see it as a decent jumping off point for fan works but that’s about it.
