Russia's ratings agency that handles video games has given The Sims 4 an 18+ age rating due to the inclusion of same-sex relationships. The game violates a law that protects children from "information harmful to their health and development."
The Sims Russia Twitter account announced earlier this week that the game had earned the restrictive rating. Previous Sims games released in the region have all been rated T (Teen) or 12+ but a law passed in 2010 is the reason for the more restrictive rating.
Ultimately, a lot of people don't think the high rating will matter due to Russia's black market for software where anyone can get anything they want for the right price.
