Parents have age ratings, but nothing that says whether a title actually helps a kid grow.

My son is turning 6. Though I played GTA as a kid, I keep wondering what kind of entertainment will actually help him grow. Now that I know GTA is rated +18 and with AI showing up everywhere, I want my son 1- gets entertained 2- by content that make him grow in a safe way. So few friends, we've built the Marble Index to measure that. Does this respect his attention? Does it grow his creativity? Does it teach anything? Is it harmless? What about online safety? You can score any content and see what it does to a kid. It's research-based, 100% free, and collaborative.
