alt Hacker NewsRatings aren't legally binding though are they? I bought games older rated than I was, and it's totally up to people's parents what they're allowed to play. Are you suggesting a 15 year old should be allowed to play the 16 rated game but not discuss it?
Can their parents also approve their discord usage?
Are you saying they need parents to buy the game, but shouldn't to join chats about the same game?
