I own a bunch of games on Steam, but my family only has one computer (capable of running them). My brother would like to play some of the games I own as well, and it would obviously be nonsensical to buy them twice when we're literally physically in the same place.
We both have a Windows account on the computer, and the accounts are set up such that they all have file system permission to access the games.
However, I would like NOT to log into my Steam account on his user account, so I'm trying to find some way to let him play the already installed games without having to do so.
Is there a simple way to do so? I read about offline mode, but it seems that it's the same as being logged in just when you don't have an internet connection.
I obviously can't start the games because after loading they just crash and say "Steam needs to be running".
