Why arent story settings/worlds like Shadowrun, Bright, or Avatar: Korra where scifi-fantasy blends

First, and just for your reference, you can find a number of examples of such blending in japanese comics and animation. For instance:

• Silent Mobius: high tech setting with demons and magic.
• Nausicaa: postapocaliptic future world part medieval, part technological (they have planes for instance and some sort of reaction engines) with some hints of magic (mostly at the end).
• Eatman: some kind of futuristic yet also fantasy world with both high tech, strange magic and sometimes even dragons.
• Darker Than Black: set in our world, some people have a magical skill that comes with a particular tradeoff. It's more of a modern espionage/mistery story than scifi, but I think it also fits the blend since some tech is also used here.
• Code Geass: Lelouch of the Rebellion: alternate scifi world with combat humanoid robots and other high tech combined with the existence of some few people with very concrete magical powers.

I don't remember more of them, but the japanese have a knack for those kind of stories. Yet in the western world we also have some franchises that kind of fall into that blend: Star Wars, Warhammer 40000, Mass Effect (where magic is presented as a high tech thing, but you can tell that is magic nevertheless). And we could say that most superhero stories also use that mixture of scifi and fantasy in varied degrees. I also happen to remember a long-running novel series called The Dresden Files in which you have an american wizard detective investigating paranormal mysteries for human and non-human clients.

As you can see, the problem is not that there's no content done in the style you're pointing at. There's quite a lot in fact, sometimes in subtle or less noticeable ways, so you just need to look more carefully or ask around if you're searching specifically such kind of fiction.

 

You could always read superhero comics- they have everything from mutants, to aliens, to wizards, to demons, to robots, to robot-alien-wizard-demon-mutants, to...
Here's a TV Tropes article about Science Fantasy: Science Fantasy - TV Tropes

 

I made a stupid amount of money doing exactly this. To be fair, I didn't know I'd done it; I stumbled backwards into my target readership.

If there's a book you want to read and no one's written it, that's the universe telling you to sit your ass in a chair and start writing.

 

I get where you're going, and after thinking about it again, I don't remember any other fiction series done exactly in the style of Shadowrun or Bright. Sure this feels a bit strange, given the potential such settings has. It's as if there's a strong bias to use certain elements only under certain settings or for certain kind of stories, something that also seems to happen a lot with the usual attachment of fantasy to medieval settings (although there's quite a bit of urban fantasy nowadays).

On the other hand, a weird fantasy series by China Miéville came to my mind: the Bas-Lag series that start with Perdido Street Station. There are no LOTR-like or mythical creatures in it, but other strange beings and magic with steampunk tech. I know is not set in a modern age like ours, but it's one of the closest thing I can think of.

Also, we could argue that magic is just some kind of science that uses ficticious elements (this point has been already discussed in Mythic Scribes), and that aliens could be your placeholder for elves, dwarves and so forth, hence the titles I've already mentioned like Mass Effect or Star Wars. Now, something I've thought myself is what would happen if the LOTR elves that had travelled to their fantasy land decided to return to our Earth? That's a premise that offer so many possibilities...

 

Andre Norton nearly always included fantastical elements in her sci-fi settings.

 

Urban Fantasy is Fantasy in the modern age- they're talking about fantasy with futuristic tech, not fantasy set on modern day Earth (or at least a planet that resembles modern-day Earth)

 

I mean, considering that the Dayu gives the example of an elf packing a laser gun along with the Legend of Korra it's clear to see that simply urban fantasy doesn't cover everything though S.T's incorrect as well.

As I see it... well, think of technology around you. It's ubiquitous. We don't really think twice about flipping a light switch, getting in a car and driving somewhere or seeing a soldier or police officer armed with a gun.

Avatar is a good example of such a thing applied to a fantastical setting. Even in the last airbender we see the effects that bending has on bending has on architecture with the Northen Water Tribe and the walls of Ba Sing Se, everyday life via the earth bending powered trams and mail chutes of the Earth Kingdom and technological advancements as seen with fire bending giving the fire nation a head start on the industrial revolution which can then spread to their non-bending citizens thanks to coal deposits and GLORIOUS STEAMPUNK.

In Korra there's the aforementioned Pro Bending showcasing those supernatural powers spreading to affect recreational sports, but we're also introduced to criminal gangs of benders in the early parts of Korra showcasing the spread to criminal elements.

Mmm.... also the time skip between the two series demonstrates a good case study of such a spread. In the Last Airbender lightning bending and metal bending were both these super special techniques. In Korra you can get a factory job lightning bending to produce power for the city and the core of the city's police force seems to be entirely made up of metal benders.

Most urban fantasy stories don't do this. The Dresden Files generally doesn't do this. It generally approaches things from the other side with the ubiquitousness of technology spreading to the magic side. Harry carries a gun. In one book the bad guys try to sell him on Ebay. The paranet is an online resource letting weak magic users and clued in muggles band together and share information on what goes bump in the night.

Not all urban fantasy stories do that either. Harry himself has a techbane field that prevents him from using any technology too modern. In Rick Riordan's Percy Jackson series demigods can't use cell phones unless they want to send up a signal flare for every monster for miles around. Harry Potter doesn't have any excuse, but not even Mad Eye Moody decides to start packing heat.

Ahem, as an aside, I would also reccomend the manga/anime My Hero Academia as an example of another series demonstrating such ubiquitousness, though there it's X-men style mutations instead of bending.

In Shadowrun both the fantasy elements like elves and magic and the sci fi elements like cybernetic augmentations and evil megacorps are just part of life enough that no one would think twice about combining them. Well, at least as far as the in game mechanics allow. They do have that whole "cybernetics eat your soul" thing going on to keep players from making terminator wizards.
