Steam users will be able to borrow and lend their games to family members and close friends in the near future through Steam's newest Family Sharing feature. With this feature, a user will be able to share his games library to a maximum of 10 authorized users. The Steam Family Sharing feature will allow close friends and family members to play one another's games while earning their own Steam achievements and saving their own game progress to the Steam cloud. It's all enabled by authorizing a shared computer.
