So I googled this first and have tried:

/home/<username>/My Games/Sid Meier's Civilization 5/Saves/
-does not exist

~/.local/share/aspyr-media/Sid Meier's Civilization VI/Saves/
-does not exist

SteamLibrary/steamapps/compatdata/289070/pfx/drive_c/users/steamuser/AppData/Local/Firaxis Games
-check all around this folder and nothing...

Any assistance would be appreciated - trying to backup some saves off a potentially failing drive.

Thanks!
