If it's games that feature things like groping underage-appearing girls, then that's a good thing.
Based on what they said here, I don't think this is suggesting an extension of what they're already doing primarily in Japanese niche games, but an affirmation on their stance.
So basically they're just officially announcing the policy they enacted like 7 months ago? lol
If they haven't talked about it publicly before, and considering the content of the article, that seems probable.
They didn't elaborate on their stance on not wanting cross platform gaming either until some months later.
