Dark magitech England-type setting. Open areas changed to narrow streets with mostly stone * architecture. Multi-tiered streets, districts maybe separated by walls. Oppressive, cramped, claustrophobic. Police are corrupt, the Queen is quite possibly a robot.
Colour schemes are black/navy blue, dark brown, and sickly green.
Inspirations are stuff like Thief (all of them), Dishonoured, BioShock: Infinite, and Paranoia (the tabletop game system)
Sisters of the Unfortunate Accuracy
An order of nuns dedicated to solving crimes exists in whatever universe.
Restrictions at character creation are “females only”
The Wet, Wild Adventures of Wendy Waterbird: The Attack of the Terror of the Giant Zombie Alien Monsters!
A campaign based entirely around tropes, themes, and over-the-top aesthetic of old b-movie or exploitation films.
Each “episode” should be a genre. Combine at own risk, genres are known to be volatile.
