Because I like playing some of these games. I don't want to be stuck with the 5 games that are officially EU approved. Asking for this kind of regulation is basically asking for legally mandated region-locks for online games. It's back to being a second class player in another region, where technically you're not allowed to play via VPN and you might get randomly banned.

Also, it's not about the children. Children don't make their own money - they only have money that parents give them. Even if these games banned children from playing them, a lot of the people complaining about it still wouldn't stop. The problem for them is that they can't make their friends stop playing these games, so they want the government to stop them instead.

I don't like when games monetize stuff like Diablo Immortal does. I hate it. But I'm certain that when legislation does arrive it'll be broad enough that other stuff gets caught up in it and the people advocating for it will just shrug their shoulders and go "lol i didn't care about games anyway".
