Hell yes! According to Engadget, Germany might block games from being purchased by miners if there is any loot boxes in game. So this means, that any games that do have it, may be forced to up their rating. I don't know how Germany's rating system works, but if this happened in the states, it would probably render games M rated because of this. That would be a big blow to anyone doing loot boxes.
I think this needs to happen everywhere. Because it's clear that kids these days still make the mistake of buying stuff by 'accident'. And no matter how you put it, buying loot boxes is essentially gambling, and I'm pretty sure in many states it's illegal to even gamble. I'm kind of surprised the US hasn't took this more seriously. It helps having countries like Germany jumping to take action.
