Recently, it was revealed that Steam adjusted its policy regarding the release of adult games on Valve’s platform. There is nothing they can do — this is the rule, and breaking it would result in the game being removed from Steam. Explicit content can still be added through DLC, which must be reviewed before release. However, patches are usually released directly without review from Valve. In related news, Steam is also quietly rejecting adult-themed games from Early Access, with developers reporting consistent rejections despite no official rule changes.
