If you have kids, they can’t play 2 completely different games on two different computers.
Steam does support that tho. That’s what Family Sharing is. And it works really well.
Now, if you wanted to play the same game at the same time, that’s on a single Steam account, that you can’t do. But I’m pretty sure you can’t do that on EGS, either. Not without 2 accounts and 2 copies of the game.
