Unfortunately there is nothing you can do to avoid Steam updates. You can always play in offline mode, but you can't install any new games.I was wondering if you guys could give me some advice here.
I am a casual gamer (which means very bad) so I don't need to go online to play.
Out of caution now I disable networking when I play games, so the Steam client can't get updated.
Does it make sense to try testing the new Steam update by creating a new wineprefix, installing Steam, let it update and finally copying the Steamapps folders from the other games so I don't risk to break anything which right now works?
I create a new virtual drive for every Steam game. This means I have multiple steam virtual drives.
So you could install Steam, install your game, update it and go offline.
From then on, just play offline.
If you want to install another game, just create a new virtual drive and install Steam again and the new game. Then follow the same steps to go offline.
As long as those virtual drives with Steam never go online, you will still be able to play.
