Two month ago Valve introduced their new "Steam Family" feature, which replaces both Steam Family Sharing and Steam Family View:

Yesterday I switched my brothers computer to the "Steam Family Beta" branch and added him to my new "Steam Family".

I expected that many of my games wouldn't be available to him, because game developers/publishers have the right to opt out of that feature.

"A game's developer controls whether a game is eligible for sharing with Steam Families. All developer settings for the previous Steam Family Sharing feature are being brought forward to Steam Families. So, if a game is currently eligible for Family Sharing, it will remain so in the new system unless the developer chooses to opt-out later."

So I was very surprised that less than 1% of my Steam library are excluded.

Most of these 48 excluded games are (surprise, surprise!) EA titles and a few Ubisoft + Rockstar Games titles:

Do you also use the "Steam family" feature? If yes, how many of your games are excluded?

He will be upset because he will not be able to play "Fresh Women"

I'll gift him his own version

I didn't even know family sharing was a thing on Steam. And yeah I'm surprised more haven't excluded their games - maybe they're just not all that aware of the feature, or it's only used by a small percent of users so they don't feel they're losing out on much revenue?

If it's an opt out feature then it may just take time for publishers/devs to realise... or they just give it some time then opt in at a later date.

I'm sure some indy devs may keep this kind of feature primarily for increased exposure (maybe some altruistically) but for most if it starts being used by too many people they may just opt out of it at a later date. (kind like when Netflix etc crack down on password sharing)

That said, looks like a neat feature, not something I will ever use myself but really does look like the best way for digital games to be shared similar to what was possible with physical. (at least assuming it doesn't block you from having a "family" from different IP address so you can share with friends)

The only reason I don't is because I don't want my little brother to become a total shut-in. If he ever gets seriously injured or paralyzed or something then I'll definitely give him access to my 1400+ game library. Great feature, though.

Did they change how the OG Family share worked?. The one issue I had with it was that only one person could play the game at a time and never both at the same time.

I don't remember the details, but I think they did indeed change that. I always thought the original limitation made sense (I thought of Family Sharing as a modern replacement for sharing the same device), but I certainly don't mind the new way either. I think the only issue is that the number of times you can edit your Steam Family has been severely limited, but that shouldn't be much of an issue in legit cases.

The old family share was pretty useless: if a family member played one of your games, the whole game library was blocked until he stopped playing.

Now you can't play the SAME game at the same time with only one licence. But now person A can play game 1, and person B can play any other game of the library at the same time. Person C can play any game of the library, A + B aren't playing at the same time. Person D can play any game of the library, A + B + C aren't playing at the same time. Person E can play any game of the library, A + B + C + D aren't playing at the same time. 

That's still better than the original method you reminded me of. Now that means I can share games to my partner and see what they like before I buy another license. 

Can't say I'm surprised at EA/Ubisoft pulling theirs out of sharing, since Ubi doesn't like us owning games, let alone licenses these days, and EA just doesn't care.

But seeing as how I haven't bought an EA game since 2016, and Ubisoft since Origins, I'm not as miffed that they opted out, since I don't buy from them these days, meaning the disappointment can never grow.
