specifically videos of adults playing Minecraft
My kids like it too, and I ended up banning those videos. I told them I'm fine with things like learning to use red stone, but they're not allowed to watch regular Let's Play or "challenge" videos. In other words, educational content is fine, entertainment needs to be vetted by us, which is a fancy way of saying "no."
If the video says, "Minecraft, but...," they're not allowed to watch it. Simple as.
So my kids are way better than me with red stone, which is awesome. They make elevators, traps, and all kinds of other stuff, which is dope. They're also not allowed to play F2P nonsense with MTX, so they tend to play creative, sandbox-y games (mostly Minecraft). They used to complain, but when the alternative is no computer use, they adapt (oldest still whines about Fortnite, but that's a hill I will die on).
