I used to read Harry Potter every summer. ( and Lord of the Rings too). Nothing wrong with young adult fiction. Some is really well done. And then some is Twilight.
None of these indicate that you have mellowed with age.As a librarian, I will recommend that if looking for the best in science fiction or fantasy, right now, Young Adult fiction is where to look. For publishing adult SF/F, publishers seem willing only to bank "sure things," but tend to be willing to look at more experimental works when it comes to "YA"-marketed fiction.
Which is not to say some tropes don't feel same-y. After all, most YA speculative fiction right now [for the past 20 years] is about plucky young ladies rising up to overthrow an oppressive regime. But that's kind of like complaining that all murder mysteries are the same because they are about a murder.
As for bagpipes and fiddle, well. [Note, neither of these have anything to do with NM inspiration, really, really, but maybe Mordheim?]
The Snake Charmer is a lady from New Delhi, who plays bagpipes accompanied by traditional Indian wedding bands and new wave techno, to play North American pop tunes. This is international multiculturalism.
And The Mudmen might be NM - they are a straight up punk band, using a bagpipe for the lead melody [electric guitar slot], AND a second bagpipe for the bass-line [electric bass slot],
And of course, you already all know about combining Mongolian throat singing and metal, to inspire a certain genre of Ash Wastes warbands:
As for looking to find movies that inspire Necromunda play? Well, someone over on reddit [what odds] put together THEIR list of movies to inspire Shadowrun play, which has some definite similarities [though I admit to being more of a Blade Runner inspiration and Dredd inspiration guy]:
Waterworld set in the Sump. Very nice.Just saw Mortal Engines. Not a bad movie. Would make for a cool Ash Wastes setting or maybe a Gorkamorka-type setting.
Now that i think about it, it could also work on the Sump Sea. It’d be something more like the Kakamura from Moana. Or the world of Gargantua on the Verdurous Planet.
Dystopian futures are cool! May this trend never end.
I'm more partial towards plucky YA main characters though (male or female alike) , but mostly because they are often not that well written these days.
The 90s did it better imo.
