I have realised what the conceptual opposite of dungeonpunk is: it is history. Dungeonpunk is sort of an anachronistic constructed setting that is situated ahistorically, to maximise appeal - in some cases it is wildly successful, expands addressable markets and broadens targeted demographics, because there is something for everyone, except actual punks. It is sort of anaesthetised and entertaining and safe, like a theme park. Not the theme park in Final Destination 3 though. Even the grotesqueries of dungeonpunk are nonthreatening and adorable. Dungeonpunk is infused with the Panglossian optimism of Voltaire's Candide, before this chapter:
... At length I became the property of an Aga of the Janissaries, who was soon ordered away to the defence of Azof (now Azov), then besieged by the Russians. (...)The Turks killed prodigious numbers of the Russians, but the latter had their revenge. Azof was destroyed by fire, the inhabitants put to the sword, neither sex nor age was spared; until there remained only our little fort, and the enemy wanted to starve us out. The twenty Janissaries had sworn they would never surrender. The extremities of famine to which they were reduced, obliged them to eat our two eunuchs, for fear of violating their oath. And at the end of a few days they resolved also to devour the women. (...) "'Only cut off a buttock of each of those ladies,' said he, 'and you'll fare extremely well; if you must go to it again, there will be the same entertainment a few days hence; heaven will accept of so charitable an action, and send you relief.'"
(Voltaire's Candide, Chapter XII, On the Russian Azov campaigns of 1695-1696 against the Ottoman Empire)
(later on there is this from chapter XXX:)
one day the old woman ventured to say to them:
"I want to know which is worse, to be ravished a hundred times by negro pirates, to have a buttock cut off, to run the gauntlet among the Bulgarians, to be whipped and hanged at an auto-da-fé, to be dissected, to row in the galleys—in short, to go through all the miseries we have undergone, or to stay here and have nothing to do?"
"It is a great question," said Candide.
