It is the single most difficult thing as a parent to put my foot down about. Or it was at first.
My son LOVES watching the YouTubers playing the (horribly developed) games and enjoys making pretend games based on what he watches (some of it, sometimes we have to skip a video). He has a lot of friends at school that play it.
I will not let my son play it. Minecraft? Sure. Minecraft has a very different system, plenty of it crap, but it's much easier to supervise and much less exploitive.
But he does let me know that he feels left out when his friends play it and he can't. He doesn't have any siblings, so I understand how it's difficult to lack that connection to peers. He has other ways he gets to connect - mine craft, local playgyms, events for children, sports.
As a parent part of the empathy is feeling that sadness that comes from his disappointment in not being allowed to play it. But I think he has started to understand as he's gotten a little older, that adults making money off of what a kid makes isn't nice, or fair, or safe.
Turkey did well here. I don't think we'll ever have something similar in the states, but I hope regulation can come about eventually.
