Is there already an app or service that will help to sync game files between devices, similar to the Steam cloud, that I can host locally? I have a NAS, which is where I download all of my "non-Steam" games to first, before copying the files over to my desktop to install. My main rig is my office desktop, but I want to copy my saves between that and my living room/travel PC similar to how Steam does for games that you have between devices. Has anyone done this? Obviously, this would work best if my living room PC is synced while on my local network, but I'm sure I could use Tailscale to sync with it from elsewhere.
