Valve has announced that it has now opened up its Family Sharing feature to all Steam users.
This feature allows a user to give other people access his/her game library and play any games in it. A user can authorize up to 10 devices for game sharing, allowing anyone that signs in on that device to access the original users’ game library. These additional users are able to create their own game saves and gain their own achievements.
There are some limitations however, when the primary account holder logs into the account all other users are given a few minutes to either purchase the game they are playing or be kicked off. Also, only one user can play a game on the account at once, with priority give to the user currently logged in.
Family Sharing has been in beta since September last year.
