Noctis was a big deal to a small audience. The game and this story here remind me of outsider art, the term of respect for paintings and sculptures and the like made by non-traditional artists. It's a whole genre of art, well studied and represented.

We have outsider art in software too, like Noctis. Not just games: TempleOS is a well known example. I'd call Dwarf Fortress outsider art too, an unusually successful example that has had a lot of influence on mainstream games.
