It's not about pedophile content. The fact is that to approve each new image with steam is a bureaucratic hell. They easily allow almost any content, but only from major studios.
It's not about our particular game if we are talking about Germany - you have adopted a new law that theoretically prohibits all 18 + games in steam. Including the new Cyberpunk, but they made an exception for it.
According to this law, Germany requires steam to check the age of the buyer, and since there is no strict verification in steam, Germany automatically bans all adult games from January, with rare exceptions.
