Unterhaltungssoftware Selbstkontrolle (USK) is a German organization responsible for the age rating of video games and other entertainment software. Established in 1994, its primary goal is to protect minors from inappropriate content by providing clear age classifications. The USK evaluates games based on their content, including violence, language, and sexual themes. The USK assigns ratings that range from "0" for suitable for all ages to "18" for adults only. These ratings help parents and guardians make informed decisions about the games their children can play. The USK's system is widely recognized and plays a crucial role in the German gaming industry.
