You are aware that there are RPGs that try to simulate real military stuff right? Grunt, Patrol, FNG E.T.C. Just because something is real doesn't mean that it people would stay away from playing around in it. Video games have also spent easily the last decade relentlessly giving you different variants of "silent American soldier fighting in the Middle East" if you're into FPS games. Hell, while we're at it keep in mind that 99.99% of people in superhero settings don't have any powers at all- just because Zatanna or Doctor Strange used magic to save your life doesn't mean you have any meaningful knowledge on how it'd work so your argument >>971910 is wrong on both the literal level (hitting helicopters with unguided rockets is a thing that happens, bazookas may be outdated but in the heat of the moment most people wouldn't quibble about whether your bazooka is actually a LAW) and the metaphorical level.
Basically, I think you've got it all wrong. It's not that stuff like urban fantasy settings wouldn't exist because people would vaguely be aware that elves are already real because Britbongman got Excalibur from a watery tart, It's that everything would have superheroes in it just like massive amounts of fantasy stuff anachronistically includes modern law enforcement despite the professional police force being a fairly recent invention.
To put it simply when it comes to media in superhero settings, take a pre-existing thing and add superheroes. Here, I'll give you some for free:
>Shadowrun
<Shadowrunners are basically the same but megacorps now have their own private superteams.
>Warhammer 40k
<Space Marines are now much more individualistic and serve as the hero characters for the Imperial Guard rather than their own faction. All factions have greater emphasis on hero units and in the RPGs Rogue Traders now all get far more cybernetics but Only War might not exist at all.
>Dungeons and Dragons
<Adventurers are now expected to wear really goofy costumes instead of armour and use stupid super-hero names. Power levels are also boosted so lone level 1 characters can easily beat packs of goblins.
>World of Darkness
<Hunter now has a compact or conspiracy dedicated to monster-hunting superheroes. Other lines often use (fictional) superheros and villians as major characters.
Etcetera etcetera, the core themes don't become unavailable any more than stories about shooting people don't become unavailable in reality, instead people just start thinking that it's perfectly normal for important people to wear exclusively spandex and go by the name "Dawnlight".
