No Sarcasm. And GoG backs up your local saves to the cloud. But going forwards each game has only 200MB, and the most recent saves get uploaded.

No, if GoG serves as a “router” for the files on your computer. You can have 200mb in gog cloud, but if you have a save on your home computer, you could use GoG to directly connect to your home computer and download saves directly from there. GoG serving to establish the file transfer connection, and your hardware serving as storage.

Would have been really cool if your older saves could be hosted by your PC. So GoG keeps the latest 200MB save in cloud but links your computers to the save on your current computer.
