EndreWhiteMane: I hope so, at this point it appears to be downloading the installed version as my install folder is now 1.9gb in size.
It needs to download and use the installer and then give us the option to save it or discard after installation.
The giant problem is making everything compatible with automatic updates on GOG's end.
I stand reminded and corrected, Steam almost certainly does this, but doesn't give you any option once the game is installed because... look something shiny!
EndreWhiteMane: Ouch, that sounds like Steam way of doing backups.
Yep, huge uncompressed files. :/
Wait, wait a moment, you can backup
Steam games?!
