Steam’s family sharing feature Steam Families is now available to everyone on the platform, letting up to six total people share games from a single library, with each individual having access to their own saved games, achievements, and workshop files.
This means that, yes, when you all sit down together in the evening, you can enjoy a hearty family meal in the knowledge that between you, you technically own six copies of the Cities Skylines Big Butt Skinner Balloon.
Each person on the account will have one of two roles: adult or child. Adults can manage parental controls, set hourly or daily playtime limits, approve purchase requests, and control store access. Valve appear very proud of making it easier for parents to spend money, streamlining the “time-consuming” task of buying games for their kids.
