CERO, or the Computer Entertainment Rating Organization, is a Japanese organization responsible for rating video games. Established in 2002, its primary goal is to provide age-appropriate ratings to help consumers make informed choices about the games they purchase. CERO uses a system that categorizes games into different age groups, ranging from "A" for all ages to "Z" for adults only. The ratings are based on various factors, including content, themes, and gameplay mechanics. CERO's system is similar to other rating organizations, such as the Entertainment Software Rating Board (ESRB) in the United States. By providing clear ratings, CERO aims to promote responsible gaming and protect younger audiences from inappropriate content.
