Violence The game is entirely text-based, so there are no violent images. However, the player can get into violent situations. These aren't usually described in graphic detail, but there are mentions of blood and wounds. There are many opportunities for the player to get into fights in London.
Scary Imagery The game has been described as Lovecraftian in tone. There are very many strange creatures in Fallen London, and many situations will give the character nightmares. The game is very atmospheric and can be creepy, but it's not horror in the traditional sense.
Sex & Nudity There is no graphic sexual content or nudity. The character can have implied liaisons with non-player characters, and enter into relationships with player characters. There is a character named Sinning Jenny, who is a scandalous citizen of London implied to be a sex worker.
Strong Language In Fallen London, Hell is a location. The word "damn" is used, but always written as "d--n."
Substance Use The player can collect many different kinds of wine and absinthe. The absinthe features in certain storylets, where the character must drink it. Wine is an item that can be traded for more valuable alcohol or sold for a few pence like most other objects in the game. There is also a substance called Prisoner's Honey that is a fantasy stand-in for opium. It gives the character strange dreams.
Consumerism The game moves more quickly and easily when the player purchases Nex, a form of digital currency that can allow the player special items or actions. However, the game is completely playable without spending money.
Discrimination Fallen London makes excellent efforts to be inclusive. The game has three gender options. The image used to represent your character is a cameo of your choice, and is always a silhouetted figure--meaning your appearance is left entirely to the imagination. Same-sex marriages are permitted.
