Comment Multiple PCs and multiple copies (Score 1) 210
Family sharing isn't a great solution. A library can only be accessed once, so you if are playing a game on your main PC someone else spouse/kid can't be on another playing a game out of the same library. The only real solution is for non-online games which is to go into Steam offline mode and the games can be accessed on two different machines.
Sony's system on the PS4 is slightly better. On machine is defined as the account's "home" system. Any content is then accessible from any other account logged into that console. You can then sign into another console with the account and access all of the content. Locking online multiplayer behind a pay service sucks, but the ability to play online is also shared with on the "home" system. So if you bought games digitally on one main account, you can easily play the same copy online with another person.
