The following is a list of video games that have been given the " Adults Only " AO rating by the Entertainment Software Rating Board ESRB , a United States -based organization which rates the content of video games to determine its appropriateness for specific age groups. Although it is not legally binding under U. Games with the AO rating are considered by the board to be suitable for players age 18 and over; AO-rated games can contain higher levels of violent, profane, sexual, or pornographic content than the next-lowest rating on the scale Mature [M], generally considered suitable for players 17 and over can accommodate. AO is the highest of the ESRB's content ratings, and restricts the commercial availability of games which carry it; all three major video game console manufacturers Nintendo , [5] Microsoft , [6] and Sony [7] refuse to allow AO-rated games to be published for their platforms, most retailers refuse to stock AO-rated games, and the popular video game live streaming service Twitch explicitly bans all games carrying the rating.
