Games with this rating contain content which the ESRB believes is "generally suitable for all ages". They can contain infrequent use of "mild"/cartoon violence and mild language. Until 1998, when it was renamed "Everyone", this rating was known as Kids to Adults (K-A).
Everyone 10+ (E10+)
March 2005
Games with this rating contain content which the ESRB believes is generally suitable for those aged 10 years and older. They can contain a greater amount of violence, mild language, crude humor, or suggestive content than the standard "Everyone" rating can accommodate, but not to the same extent as the "Teen" rating.
Teen (T)
1994
Games with this rating contain content which the ESRB believes is generally suitable for those aged 13 years and older; they can contain moderate amounts of violence (including small amounts of blood), mild to moderate use of strong language or suggestive themes, sexual content, and crude humor.
Mature (M)
1994
Games with this rating contain content which the ESRB believes is generally suitable for those aged 17 years and older; they can contain content with an impact higher than the "Teen" rating can accommodate, including intense and/or realistic portrayals of violence (such as blood, gore, mutilation, and depictions of death), stronger sexual themes and content, partial nudity, and more frequent use of strong language.
Adults Only (AO)
1994
Games with this rating contain content which the ESRB believes is suitable for those aged 18 years and older; they contain content with an impact higher than the "Mature" rating can accommodate, including strong sexual themes and content, graphic nudity, or extreme portrayals of violence. The majority of AO-rated games are adult video games with pornographic content: the ESRB has seldom issued the AO rating solely for violence.
