As a fully grown adult, I like the concept of this game.
Mind you, the game has a clear 18+ rating and warnings, so people know what they're downloading. Let's be real: kids today ignore age ratings and will download games anyway, unless they live in a country like mine that strictly blocks access for those under 16.
Also, the developers made this for a specific, mature audience, and it's not their fault if kids find a way to play it.
I understand you want to act as the moral compass here, but let's be realistic.
