I had an interesting discussion last night with some friends around the table about sword & sorcery old school rpg's like Original Dungeons & Dragons as well as retroclones such as
Astonishing Swordsmen & Sorcerers of Hyperboria, Labyrinth Lord, Basic Fantasy,
Dark Albion,
Lamentations of the Flame Princess,
Adventurer, Conqueror, King, Fantastic Heroes & Witchery and lots of others. The conversation got bogged down into the definitions of the genre of sword & sorcery is & how I was doing it wrong. Let me go on record as saying that you as the dungeon master define the world; the players fill it with exploits of their PC's. Here's why.

Sword & Sorcery is defined as follows;"
Sword and sorcery (
S&S) is a
subgenre of
fantasy generally characterized by sword-wielding heroes engaged in exciting and violent conflicts. An element of
romance is often present, as is an element of
magic and the
supernatural. Unlike works of
high fantasy, the tales, though dramatic, focus mainly on personal battles rather than world-endangering matters.
[1] Sword and sorcery commonly overlaps with
heroic fantasy.
[2]
A film genre tangentially related to sword and sorcery, at least in name, is
sword-and-sandal, though its subjects are generally oriented to biblical times and early history, instead of fantasy. Not to be confused with
cloak and dagger or cloak and sword, which are alternate genres."

Another reason why I draw from the swords & sorcery genre is because of the femenist perspective of it;"Despite the importance of C. L. Moore, Leigh Brackett,
Andre Norton, and other female authors, as well as Moore's early heroine, sword and sorcery has been characterized
[by whom?] as having a strongly masculine bias. Female characters were generally
distressed damsels
to be rescued or protected, or otherwise served as an inducement or
reward for a male hero's adventures. Women who had adventures of their
own often did so to counter the threat of rape, or to gain revenge for
same.
[24][27] Marion Zimmer Bradley's
Sword and Sorceress
anthology series (1984 onwards) attempted the reverse. Bradley
encouraged female writers and protagonists: the stories feature skillful
swordswomen and powerful sorceresses, working from a variety of
motives.
[28][29]
The series was immensely popular and Bradley was editing her final
volume at the time of her death (the series continued under other
editors).
Jessica Amanda Salmonson
similarly sought to broaden the range of roles for female characters in
S&S through both her own stories and in editing the
World Fantasy Award-winning
[30] Amazons (1979) and
Amazons II (1982) anthologies; both drew on real and folkloric women warriors, often from areas outside of Europe.
[31][32]
Today, active female characters who participate equally with the male
heroes in the stories are a regular feature in modern sword and sorcery
stories."

For me I draw from both sword & sorcery and the sword & planet genre freely;"Other pulp fantasy fiction — such as Edgar Rice Burroughs'
Barsoom series and
Leigh Brackett's
Sea Kings of Mars — have a similar feel to sword and sorcery, but, because alien science replaces the supernatural, it is usually described as
planetary romance or
sword and planet, and considered to fall more in the area of science fiction.
[22]
Despite this, planetary romance is closely aligned with sword and
sorcery, and the work of Burroughs, Brackett, and others in the former
field have been significant in creating and spreading S&S proper.
[23]
Sword and sorcery itself has often blurred the lines between fantasy
and science fiction, drawing elements from both like the "weird fiction"
it sprang from.
"
So how is Accursed Atlantis different from the run of the mill material out in the wilds? Well as a setting it draws deeply from pop culture whist still using tradition material. Accursed Atlantis has a number of alien races, near humans, mutants, and others all vying in an entropic wasteland after it all went to hell. The technological level is someplace between a pulpy late 1800's all the way through 1960'sscience fantasy levels on the high end. And unlike other settings the relics are quite literally all over the place and that's the problem. High amounts of magickal pollution, Lovecraftian horrors, dimensional instability, space gates, mutation, magick, and worse are stalking the world unchecked. Accursed Atlantis is a world where warfare is common & survival is a matter of sword or sorcery. Humans are on the menu and anything can happen.

Basically Accursed Atlantis started out as my OSR sand box & its grown into a fully fledged campaign setting where I drop anything into without 'breaking' it. Here there are strong ties with ancient mythology and weird twists on some of the usual themes. There is black powder weaponry, lots of fighting women & men, gods walk among men, etc. In other words many of the themes of traditional sword & sorcery are there but with my own twists. 
So what's with all of this explaination and exposition about Accursed Atlantis? Because as a dungeon master I'm defining the OSR at my table on my terms not on an authors terms, not on a designer's terms, or a publisher's terms. Its my world there will be lots more to come as the days roll on.
