I think even the Nintendo Switch is more fair about it, but I haven't checked it directly
This has burned me really badly. I had an account with hundreds of Steam games, and then my dad got hooked on some of the VR games I'd bought and set up on a Vive machine in the living room upstairs. I had to make a new account to be able to play new games. Then my nephew got hooked on one of the games on the new account, so I ended up giving it to him and making a third account for myself. That one only has a couple of games on it, since I've mostly just transitioned to playing stuff on GoG and the Nintendo Switch
In most cases the regular plan is the family plan because most people live in a family and the extra features don’t harm people with individual accounts at all.
What other stores have a family plan at all?
