ESRB

The Electronic Software Rating Board (ESRB) is the American organization which rates the video games released in North America. In Europe it is the Pan European Game Information (PEGI). The ESRB has been widely criticized for its lack of strictness, with its critics stating that the ESRB rates games much lower than it deserves, so more copies of the game will be sold.

Rating Scale
The rating system is as follows.

Early Childhood
Titles rated EC (Early Childhood) have content that may be suitable for ages 3 and older. Contains no material that parents would find inappropriate. It is the equivalent of a TV-Y rated TV show. No games created by Nintendo are rated EC for unknown reasons, the others were Rated M and Rated AO. In April 2018 the rating was retired

Everyone
Titles rated E (Everyone) have content that may be suitable for all ages. Titles in this category may contain minimal cartoon, fantasy or mild violence and/or infrequent use of mild language. It is the equivalent of a G rated movie.

Everyone 10+
Titles rated E10+ (Everyone 10 and older) have content that may be suitable for ages 10 and older. Titles in this category may contain more cartoon, fantasy or mild violence, mild language, and/or minimal suggestive themes. It is the equivalent of a PG rated movie.

Teen
Titles rated T (Teen) have content that may be suitable for ages 13 and older. Titles in this category may contain violence, suggestive themes, crude humor, minimal blood and/or infrequent use of strong language. It is the equivalent of a PG-13 rated movie.
