SFS

Acronym for Standard Fantasy Setting. You got your elves, dwarves, goblins, swords, and magic. If you can't talk about it without referencing the Lord of the Rings or Dungeons & Dragons, it's probably in the SFS.

"I'm making a game about dwarves, but it's not in the SFS cause they're like actual dwarves who work as tax accountants."
