The obscure lore is inferred from both text and subtle gameplay elements and is still very well within bounds of what we see in game (outside of references to other games like Patches and the moon sword).
Vermis lays out vague facts that are not tied to anything existing in reality, the reader only knows that all of that works in a videogame, but what kind of the game it is will vary differently from person to person - it can be an action-rpg like dark souls, it could be a dungeon crawler like Waxworks, it could be a party-based narrative adventure like Betrayal at Krondor (definitely less railroaded though) and so on and so forth. Same for the setting - It could be a renaissance Silent Hill, it could be a Warhammer Fantasy-like "carnage everywhere" fest, it could be a down-to-earth low-fantasy... There are too many factors that are left to imagination in Vermis. Videogames do not function that way - they need a strict ruleset, a fixed setting and a coherent narrative - something that will make Vermis less than the book describes it to be.
