Steam still bans r18 content arbitrarily, usually localizations of Japanese visual novels. For example, Steam banned CHAOS;HEAD NOAH less than 60 days before its release date without explanation and only relented because of community protest. The remastered version of the game released doesn’t even contain r18 content though the original does. Even more puzzling, Nintendo allows the same version of the game to be sold on their site for the Switch. WTF? The C;H Noah is too adult for Steam, but OK for Nintendo?
