CERO is a rating system that is exclusively used in Japanese video games, except for PC games (which are rated by the EOCS, or the Ethics Organization of Computer Software). It was originally founded in July 2002, though it wasn't officially recognized as its own organization until 2003. Like other video game rating systems such as the ESRB, it determines the content of the video game and what ages it's best suited for.

This rating indicates that the game contains some adult content and therefore minors must get permission to get games with this rating. And it's recommended that you are 17 if you play any game whit this.

This rating indicates content ONLY for those ages 18 and over. Nobody under this age can purchase the game.

In addition, cultural factors unique to Japan have caused discord among this series. Some games have gotten A's here but received Mature (17+), while on the other hand, some games are getting Teen (13+) here while getting a Z rating in Japan (I.E. Infamous).
