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?
