I like to keep a backup of any DRM free games on a local drive, less because I intend to play every single one of them, and more because data hoarding is the only joy I have left that doesn't cause me pain.
usually, anyway.
I hurt myself to add every game to my account thinking, somehow, that there would then be a way to then download them one by one automatically in the background. As far as I can tell, I was wrong, but I'm hoping I missed something.
For reference, I would prefer if it could download each package into a unique subdirectory, as many of the games just have you download "game.zip" or "installer.exe" from the download page.
