Adults Only Rating

Go To
Your game got this rating? Fare thee well, profit...unless we're talking Steam.

"Adults Only is by far the rarest rating with only 27 games rated as such. Now, there's not really a ton of games rated AO for a few reasons, the first is the fact that most AO rated games are basically..."
(leans on a TV that displays the word "PORN")
"Another being the fact that all console manufacturers have a policy against AO games, stating that they aren't allowed on the platforms, and similarly most retail chains won't carry products rated AO."

One of the age ratings of the Entertainment Software Ratings Board. This rating is aimed at people who are at least 18 years old. No one under 18 is permitted to buy games that are rated AO, though it is not legally binding in the United States (it is in some Canadian provinces, however). This is why it is termed "Adults Only".

You might be confused as to why the top rating is only one year above the Mature Rating. Generally, only games with pornographic content, or at least borderline porn, give a game the AO rating, and it's quite possible the highest rating was made to conform with general pornography laws, when the ESRB otherwise felt that 17 is the true developmental cutoff. However, there are a few games that have this rating solely because of their violent content.

One would think that if a game gets a lot of attention and money for being rated M, then surely rating it AO will make it sell even better, right? Not quite. Similar to an "NC-17" rating, an AO rating is a death sentence to a game's financial viability, as every large retailer will refuse to stock AO games, and the current major console makers refuse to license them due to the association of "adult-only" ratings with pornography. In addition to the above, livestreaming website Twitch has outright stated that they prohibit AO-rated games from being streamed on their site, although any M-rated versions of certain games (such as Grand Theft Auto: San Andreas and Fahrenheit: Indigo Prophecy) are still allowed. On the other hand, places like Steam are finally allowing AO rated games onto its service, and GOG is fine with hosting select AO rated titles.


The Other Wiki has a full list of AO-rated games (there are currently 29 of them).
