Contemporary
Alternate Earth, circa 1990s, but also including '80s roller skates, encounters of the sexy AND alien kind, and furries.
Contemporary Noir
Alternate Earth, circa 1920s, gangsters, crime syndicates, murder, boxing, detectives...almost always raining. This genre is pretty much exclusively reserved for
Connor and his crew--which also features multiple Were-species, Vampires, Fae, Witches, and D/s action.
Paranormal
Cryptids, good and bad supernatural entities, and the agencies trained to deal with them.
Shifters
Species who shift between full to half animal forms and human ones (part-time furries! LOL), including CatKynd, FoxKynd, Serpentians, and a number of varieties of Birbiankin and Gilled as well. The
Shiftless series is currently going here, though some of it takes place with steampunk technology and involves magic users as well.
Tiger's Catch - Novella
Xenology
...Tentacles. Also featuring other less human-like species in Luridity. And tentacles.
Extranatural Powers
Superheroes, superhumans, telepaths, elementals, and "mutants" not derived from biopunk engineering. Both training and persecution exist in this genre, depending on the planet, so check the tags first.
