Does Steam allow NSFW games? The rules for games, mods, avatars and artwork

Steam allows NSFW games. Valve’s rules for developers do not ban adult content. They ban “adult content that isn’t appropriately labeled and age-gated”, which leaves labelled and age-gated adult content permitted. Explicit games have been sold on the store on that basis since September 2018.

Two limits sit on top of that permission. Games cannot use nude or sexually explicit images of real people, and since July 2025 Valve also prohibits content that “may violate the rules and standards” of its payment processors, card networks and banks.

The community side of Steam is stricter than the store. Profile pictures, artwork, screenshots and Workshop items fall under rules written for what Valve calls an “all-ages and international community”, and sexually explicit uploads are not allowed there.

This page sets out both sets of rules. It is written for players and for developers deciding whether Steam will take their game. It describes Valve’s published rules as they stood on 11 October 2026.

Key points

• Adult games are allowed on the store when they are labelled and age-gated.
• Real people are excluded. Nude or sexually explicit images of real people cannot be published.
• A 2025 rule added a second limit, tied to payment company standards and aimed at “certain kinds of adult only content”.
• Adult games are hidden by default. A player has to opt in.
• Avatars, artwork and Workshop uploads must not be sexually explicit.
• One exception applies to uploads: game content posted in that game’s own hub.
• The United Kingdom and Australia have a credit card age check.

What Valve’s rules for developers say

The rules are in the Steamworks onboarding documentation, under the heading “What you shouldn’t publish on Steam”. The list has fifteen items. Four of them govern adult content.

Item 3 is the permission in negative form. Items 2 and 8 are fixed lines. Item 15 is the one that moves, because it points to standards written by other companies.

Two other items are sometimes applied to adult games. Item 6 prohibits content that “violates the laws of any jurisdiction in which it will be available”, and item 7 prohibits content that is “patently offensive or intended to shock or disgust viewers”.

How Steam came to allow adult games

Before 2018 Steam did not sell fully explicit games.

• June 2018. After a period of inconsistent decisions, Valve announced it would “allow everything” on the Steam Store except content that was illegal or “straight up trolling”.
• September 2018. Valve introduced the filters that make that possible. Game Developer reported that the new tools came with a requirement that developers describe the mature content in their games.
• 14 September 2018. Negligee: Love Stories was released as the first fully uncensored adult game under the policy. PCGamesN reported that it was not sold in 28 countries.
• 16 July 2025. Valve added item 15 and removed a number of adult games.

We cover the longer story in a short history of adult games.

Did Steam remove NSFW games? The 2025 rule

It removed some, and it did not remove the category.

In mid-July 2025 the fifteenth item appeared on the list. GamingOnLinux and AUTOMATON reported the change alongside the removal of a set of adult games from the store. Valve’s explanation was that it had been notified that certain games might violate the rules of its payment processors and the related card networks and banks.

The rule’s weakness, from a developer’s side, is that it does not say what those standards are. It says “certain kinds of adult only content” and stops. A developer cannot read the rule and know whether a given theme is inside it.

We set out the events in order in NSFW games removed from Steam and itch.io: a dated timeline, and the mechanism behind them in the Visa and Mastercard adult content policy, explained for games.

How adult games are labelled and gated

Item 3 depends on two things the store does.

Labelling. When a developer submits a game, they declare which of Steam’s mature content categories apply and describe the content in their own words. The description is shown on the store page.

Gating. Games in the last category do not appear in search, recommendations or tag pages until a logged-in player ticks Adult Only Sexual Content in store preferences. The steps are in how to see adult games on Steam.

A developer who labels an adult game as something milder breaks item 3. The label is the condition the permission rests on.

What the store does not allow

Read together, the list rules out the following in a game.

1. Real people. No nude or sexually explicit photographs or footage of real individuals. Adult games on Steam are drawn, rendered or animated.
2. Anything that exploits children. Item 8 says “in any way”. Valve does not publish how it assesses characters who look young.
3. Unlabelled adult content. An adult scene in a game declared as non-adult.
4. Content illegal where the game is sold. A developer can exclude countries, and some games are withheld from some markets for this reason.
5. Content caught by item 15. Undefined, as described above.

Valve reviews each game before release. The onboarding rules are the published standard, and the review is where they are applied.

Does Steam allow NSFW avatars, artwork and screenshots?

Here the answer changes. Steam’s rules for discussions, reviews and user generated content open by saying that community content must “be appropriate for everyone using Steam’s all-ages and international community”.

Under the heading “User-Uploaded Content”, the rules cover “screenshots, player artwork, custom profiles, and workshop items”. The first instruction is “Don’t upload inappropriate content”, and the examples are:

• “Real or disturbing depictions of violence”;
• “Content that exploits children in any way”;
• “Sexually explicit content. This does not forbid game content posted in its own game hub.”

The second sentence of that last example is the whole exception. A screenshot from an adult game, posted to that game’s community hub, is not forbidden by the rule. The same image used as a profile picture, a profile background, or artwork posted in another game’s hub is.

A second instruction closes the gap between the two: “Don’t bypass Steam’s Mature Content Preferences”. Steam explains that every player “has account preferences related to mature content”, and that these “determine the types of games and community content that are shown to that player”. An upload arranged to show adult material to people who have not opted in breaks this instruction even if the material came from a game.

Does Steam allow NSFW mods?

Workshop items are named in the same rule, so the same answer applies. A sexually explicit Workshop item is inappropriate content unless it is game content in its own game’s hub, and it must not bypass Mature Content Preferences.

The game matters here. An adult mod in the Workshop of an all-ages game puts explicit content in a hub where the game itself has none. On our reading, that is the situation the rule is written against.

Valve’s published rules say nothing about patches or mods hosted outside Steam. This page does not cover them.

What happens when community content breaks the rules

The rules describe three levels.

1. Content removal. The upload is taken down, usually with a notification and an option to contact support.
2. A cooldown on the feature. Steam’s own example is the avatar: “if an avatar is removed, the account will lose the ability to upload a new avatar until the cooldown has expired”.
3. Loss of all community features. Accounts that “repeatedly violate these guidelines” risk losing them temporarily or permanently.

Groups are covered too. Those that allow violations “may be removed”, and the accounts involved in uploading may be restricted.

Steam admits the judgment is imperfect: “we’re not always going to get it right”. Moderation messages include a link to appeal. It also answers the most common complaint in advance: “the existence of rule-breaking content does not excuse or permit other violations”.

Why adult games may still not appear

A player who cannot find adult games on Steam is usually running into one of four things, none of which is a ban.

• The preference is off. It is off by default on every account.
• The player is not logged in. The preference belongs to an account.
• An age check applies. Since 29 August 2025 Steam has required a valid credit card on United Kingdom accounts before showing mature content, as TheSixthAxis reported. Australia followed in September 2026. See Steam age verification and adult games.
• The game is not sold in the country. See Steam “this content is not allowed in your country”.

What this means for adult game developers

Steam is open to adult games and less predictable than it was before 2025. Five points follow from the rules.

1. Declare the content accurately. The whole permission depends on labelling and the age gate.
2. Use no real people. Item 2 has no exceptions in its text.
3. Treat item 15 as an unknown. Its standards are not published, and a game can be refused or removed under it.
4. Keep store assets and community posts clean. The studio’s own avatar, group and announcements sit under the community rules, where explicit content is not allowed outside the game’s hub.
5. Do not depend on one store. A game that Steam accepts today can be affected by a rule Valve does not control. Other routes are set out in where adult games can be sold in 2026 and in DLsite vs Steam for adult games.

What is still unknown

• What item 15 covers. Valve has not published the payment company standards it refers to.
• How Valve assesses the apparent age of drawn characters. Item 8 is one line long.
• How the upload exception is applied in practice. The rule says game content in its own hub is not forbidden, and gives no examples.
• Valve’s position on patches hosted elsewhere. The published rules do not mention them.

How this page was put together

The developer rules are quoted from the Steamworks onboarding documentation, and the community rules from Steam Support’s rules and guidelines page, both read on 11 October 2026. Neither page carries a revision date. The dates in the history section, and the account of July 2025, come from the news reports in the sources.

Nothing here is a first-hand account of Valve’s review. The category table repeats the one in our guide to Steam’s filters.

This page was written on 11 October 2026 and will be updated when Valve changes either set of rules. To report an error, see the corrections standard.
