  • Rating Pending - Titles designated as RP (Rating Pending) have not yet been assigned a final ESRB rating. This icon appears only in advertising, marketing and promotional materials related to a game that is expected to carry an ESRB rating. The RP is replaced by a game's rating once it has been assigned.


The following list of content descriptors is provided by the ESRB. Some descriptors may be prefixed by "mild" or "strong" to indicate the severity of the descriptor if not already prefixed by "strong" such as the strong language descriptor. Additionally, some descriptors in use do not appear on this list such as the edutainment descriptor.

However, the relationships between descriptors and ratings is not explicit, making such relationships ripe for exploration.

Games rated early childhood are not allowed to contain any of the descriptors. As such, the entire descriptor list provided by the ESRB should be avoided for those creators wanting an early childhood rating for their game.

Leisure Suit Larry: Magna Cum Laude
Uncut and Uncensored
The descriptors related to substances are somewhat good predictors of rating: games rated everyone may contain the references to alcohol and tobacco descriptors as well as the use of alcohol and tobacco descriptors. Games rated teen may contain the use of alcohol and tobacco descriptors and the drug reference descriptor but not the use of drugs descriptor. Games rated mature may contain the use of drugs descriptor.

The violence descriptors are bad predictors of rating: games rated everyone may contain the comic mischief, cartoon violence, fantasy violence, violent references, and violence descriptors, but are not allowed to contain the intense violence and sexual violence descriptors. There are four ratings above everyone.

The strongest predictors of rating are the sexuality and nudity content descriptors.

Games rated everyone may contian the mild suggestive themes descriptor, but are not allowed to contain the suggestive themes, sexual content, sexual themes, sexual violence, strong sexual content, partial nudity, or nudity descriptor. The suggestive themes descriptor itself contains the word mild, so mild suggestive themes may be indicative of suggestive themes that are milder than mild.

Games rated everyone 10+ may contain the suggestive themes descriptor, but are not allowed to contain the sexual content, sexual themes, sexual violence, strong sexual content, partial nudity, or nudity descriptors.

Games rated teen may contain the partial nudity descriptor, but are not allowed to contain the nudity descriptor, which is reserved for mature and adults only games.

There is no unique descriptor associated with an adults only rating. That is, there are no descriptors associated with an adults only rating that are not allowed to appear in mature-rated games. A possible exception is Riana Rouge, which contains a realistic blood and gore descriptor. Perhaps the prefix realistic was added to the blood and gore descriptor because no intense violence descriptor was available at the time of rating. Another possible exception is the mature sexual themes descriptor given to a non-game: Playboy Screensaver: The Women of Playboy.

Riana Rouge
The ESRB does not make the relationships between content descriptors and ratings explicit. As such, the relationships explored above may or may not endure. However, over the short life of the ESRB, the relationships between ratings and some of the content descriptors, particularly those involving sexuality and nudity, have been predictable.
