>Even with all the monsterpedia entries, established characters and distinct regions?
Yeah. Part of it is how you are first exposed to the IP. With MGQ, you play the game and you are shown a rather complete story that ties most stuff together at the end, with a specific MC.
With MGE you come into contact with either the fanfics themselves or the threads, where greens are posted.
There are two takeaways. First is that having established characters isn't really a bonus. You could write a fanfic about Luka and his girls, or about some random guy. Luka takes the most spotlight in MGQ, to the point that anything that happens needs to be crosschecked with what he's doing. Having such an established background doesn't leave that much room to come up with stuff.
While the MGE has a lot of named characters, they aren't much of the focus of the game. Most of them are either gods that have more of a passive influence on the world, or some character that has influence on the scale of city, not worldwide, which leaves much more room for other stuff happening without interacting with them. The MGQ world is pretty small, you go through all of it in both games no problem, and you end up knowing all that's happening.
This is also true in therms of scale. Luka goes sicko mode in multiversal terms, hard to imagine what else would there be left to do or tell. The story of a small town mayor helping bring his people and the nearby alraune population isn't really as compelling in MGQ as it is in MGE.
Which leads me to the second thing. They have vastly different audiences. Even in the monstergirl community, MGE attracts people that want to write from the start, while MGQ presents itself as a videogame that's consumed and that's about it. WHoever still want to do creative work for it usually goes the route of pics, comms or doujins, rather than "cringy" AO3 fanfics.
