So you’re trying to say it’s a survivorship bias? Well, I did turn right, and everyone I know from childhood has turned out alright as well, except for a few who had problematic parents. So games did not cause harm, but rather irresponsible parents (or, to be fair, parents with mental problems...).
What if these kind of games are a problem for kids with shit parents, or kids who are in a dark places for other reasons, like bullying? The same with like drugs, gore, or porn? Should we just ignore those kids? Or what do you propose?
Well, I think you’ve argued yourself into a corner there. Shit parents aren’t going to deny access to video games which are too mature for their children, so a rating system should isn’t going to help
