SteamDB creator Pavel Djundik noticed that Valve is working on new family settings on Steam. There are few details yet, but it is known that there are three functions.

▫️Family groups.
▫️Time limit in games per day.
▫️Children will be given the opportunity to "request" games.

Steam now has a "Family View" feature. Thanks to it, parents can restrict children's access to the store, individual games and communities. The Family Library Sharing function is also available on the site, which allows users to share games with other accounts — with family members or friends.
