Who do you think we are, a bunch of criminals?

It depends on what platform you're looking for.
Your closest bet when it comes to console games would be something your country has banned but in all likelihood it's probably not something that objectionable in content matter (like, Mortal Kombat or something).
So your best bet is something for PC... idk where you're gonna look except something really niche. ┐(ﾟ～ﾟ)┌
If you're really just looking for fucked up content matter, idk, go play Demonophobia or Rapelay. There's also Sad Satan (lol), you've already heard of it I trust. Good luck finding the 'unclean' version. (＾Д^)
