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 , which is generally considered suitable for players 17 and over, can accommodate. AO is the highest and most restrictive of the ESRB's content ratings, and dramatically impacts the commercial availability of games which carry it; all three major video game console manufacturers Nintendo , Microsoft , and Sony Interactive Entertainment 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.
Nintendo , a seasoned veteran of the video game world, is known for Mario , Zelda , and Kirby , not M-rated gore fests. The world might implode if the next Mario game included Princess Peach the prostitute and Toad the serial killer. Similarly, Zelda fans might have to change their pants if Skyward Sword is filled to the brim with blood, guts and horror. It's just not what gamers have come to expect from Nintendo. Naturally, there aren't many "mature" games on the Nintendo Wii. Most people can't even think of five M-rated Wii games. This is where Game Rant comes to the rescue.
Edit for Clarity:. Our goal at Twitch is to create a safe, welcoming, inclusive community platform where everyone can feel comfortable and have fun. From time to time, we update our Rules of Conduct RoC in pursuit of this goal and to match emerging issues in the video game industry.
