With the new sexual content filters in place, Steam's new policies have apparently taken effect.
Back in June,
Valve announced that it was no longer going to police what could and couldn't appear on Steam, removing games only if they were illegal or "straight-up trolling." This, we speculated, meant that Valve would be ending its rule disallowing "pornography," and that appears to be the case.
After adding new filtering tools which allow users to opt into seeing "Nudity or Sexual Content" and "Adult Only Sexual Content" on the Steam store (those are two separate categories), Valve has approved
Negligee: Love Stories for release this Friday, a game which was previously
held up while those tools were being developed.
...
If "Nudity or Sexual Content" and "Adult Only Sexual Content" are among your interests, the option to see games tagged as such in the Steam Store can be selected in the 'Store Preferences' menu, which is reached by clicking your display name in the upper-right hand corner of the client. If you're a parent who
doesn't want those tags visible, you may be best off not only keeping those boxes unchecked, but entirely blocking access to the Steam Store under the 'Family' tab in the main Steam settings.
