Valve now allows games with «adult-only sexual content» in the Steam store. Steam hides these games by default and they won’t show up in searches. But you can enable these «adults only» games in your Steam account settings if you wish.
Yes, Steam now allows adult-only sexual content
Steam has always allowed certain types of sexual content. Popular games like The Witcher 3, include nudity and casual sex scenes, just like the R-rated film.
Valve has traditionally not allowed «pornographic» games. Valve has recently been threatening to remove games that it considers pornographic. After some discussion, Valve decided they didn’t want to be the judge, that it wasn’t pornography, or that the steam store should and shouldn’t sell.
Eric Johnson of Valve outlined the new policy on his blog on June 6, 2018:
Valve shouldn’t decide this. If you are a player, we do not have to choose for you what content you may or may not purchase. If you are a developer, we do not have to choose what content you are allowed to create. These choices must be yours to make…
With this principle in mind, we decided that the right approach is to allow everything in the Steam Store, except for things that we consider illegal or just trolling. Taking this approach allows us to focus less on trying to control what should be on Steam and more on building these tools to give people control over what kind of content they see.
In other words, the couple now allows games with adult-only sexual content that was previously considered pornography. Only games that are illegal or «trolling» are banned.
However, Steam hides these game types by default and they won’t show up in the Steam store even if you search for their exact name. Instead, you’ll see a message that some titles have «been excluded based on your preferences.»
You will still see these games if you link directly to their product pages from another website, regardless of your Steam preferences. You will need to review the content warning first.
