Depending on the country, it will not be shown on steam. Most likely germany and sometimes turkey will sort it out by default.

Yeah Germany has some bad history about that, but its mostly related to the war in the past.
I had to change my country on Steam, because Steam somehow had my country (Denmark) changed to Germany because it once was under german rule, which affected how i was allowed to use my money.
But its not about the country im talking about, its the fact that Steam has some restrictions on what is allowed on Steam.
Those restrictions are like bestiality, characters looking like a minor (because of Loli), and also no content related to incest.
