Empire of Sin is a strategy and role-playing video game developed by Romero Games and published by Paradox Interactive. It was released on December 1, 2020 for Microsoft Windows, macOS, PlayStation 4, Xbox One, and Nintendo Switch. In the game, the player takes the role of one of several mob bosses inspired by real-life figures in Chicago during the Prohibition era. The player, acting through their boss character, must decide and direct the actions of their underlings to take over rival businesses such as clubs and brothels, recruit new members to their cause, and defend their empire against other bosses and the law in a bid to take complete control of Chicago's underworld. Gameplay Empire of Sin is a real-time strategy game with the player taking the role of a crime boss in the Prohibition era starting in 1920, one year after the passage of the Eighteenth Amendment, and trying to gain control of Chicago by 1933 (when Prohibition is abolished). The game starts with the player selecting a boss character, several of which are directly modelled on Prohibition-era criminals such as Al Capone, Dean O'Banion, and Stephanie St. Clair, while others, such as Goldie Garneau, are fictional but take inspiration from the era. Each boss can form a "crew" of up to 16 underlings from 60 potential ones to help manage their empire of criminal rackets, such as speakeasies, casinos, and brothels, protect them from the law and rival mafia gangs, deal with unforeseen problems (such as protestors shutting down a brothel or an undercover federal agent visiting a speakeasy), and work to extend their gang's influence by taking over the rackets of other bosses. Rackets can be upgraded with cash to improve their security, increase their profits, and better conceal themselves from potential enemies. Bosses must regularly consult their business ledgers through the in-game menu to track how well their rackets are operating and whether any adjustments or upgrades need to be made. The city of Chicago is divided into neighbourhoods, each of which has rackets controlled by other gangs, vacant properties that can be purchased and converted into rackets, and decrepit buildings occupied by small criminal gangs who must be wiped out in combat before the building can be put to use, ransacked for profit, smashed up to temporarily make it unusable, or razed to the ground so that no one can use it.
