The ESRB (The Entertaintment Software Rating Board) is a rating system for North American games. The range of ratings are from EC (Early Childhood) to AO (Adults Only). The ESRB has many content descriptors that help guide the rating choice. The content descriptors can have the word 'mild' in front, if there is not much of it or 'stong' is there is more than usual of it in the game. Mortal Kombat created the ESRB for it's gorey fatalities. Mainly Sub-Zero's Spine-Rip fatality.
Early Childhood (or EC) is the lowest rating for games. This rating is usually used for educational purposes. It is one of the most uncommon ratings seen. Suitable for ages 3 and up.
Everyone (or E) is the most common rating for games. Games with this rating usually have Comic Mischief. This rating was formerly Kids to Adults (or K-A). Suitable for all ages .
Everyone 10+ (or E10+) is a rating suitable for players 10 and up. This rating usually has Fantasy or Cartoon Violence.
Teen (or T) is the lowest 'mature' rating for games. Games with this rating usually have Blood, Language (Sometimes Mild), and Violence. Suitable for ages 13 and up.
Mature (or M) is the most common 'mature' rating for games. Games with this rating usually have Blood and Gore, Strong Language, and Intense Violence. Suitable for ages 17 and up. Retailers are supposed to restrict these from children under 17 but most just sell the games to them anyway.
Adults Only (or AO) is the least common 'mature' rating for games. This rating appears on games that are very inappropriate for anyone who is not an adult. Suitable for ages 18 and up. Retailers do restrict these games to people under 18, unlike the Mature rating, which the retailers sell M rated games to children anyway.
Kids to AdultsEdit
Kids to Adults (or K-A) is the former E rating for games. Only PlayStation games had this rating.
Rating Pending (or RP) is only used in advertising when the ESRB is coming with a rating for a game.
