Steam Family Sharing will allow game sharing on accounts that also share the same computer! How awesome is that?!?! No longer will your son or daughter have to use your personal Steam account to play games. You can authorize them to access your games on thier personal account and they can now play your downloaded games. The best part about it is that they will also have their own saved files and achievements tied to their accounts and won't affect your personal account what so ever.
I'm definitely looking forward to this. I use my son as an example because he'll log on to my account to play L4D 2. I don't mind, but if he's logging on hours on my account and earning achievements for me, it makes my profile a bit of a fake and that I do mind. With Steam Family Sharing, I won't have to worry about that anymore.
Steam Family Sharing enters beta testing in mid September and should go full blown live shortly thereafter. What do you guys think of the idea to share games? Let's hear your thoughts! Later!
