Just did a GOG survey that focused on the idea of a paid membership option on GOG. Seems they're determining what people would be willing to pay extra for. Some of the options were
- a tool for backing up offline installers
- ability to install previous versions of a game
- extra insight into the preservation work they're doing.
- voting rights on games to bring into the preservation program.
And others that I can't remember.
That's great, but maybe we should stop talking about you. People pay for Steam, Netflix and many other services because they don't want to write scripts. They want something convenient and easy to use. They also want additional functionality. You said how you back up save files, but nothing about achievements, time tracking, friends, screenshots sharing, guides, parties, etc.
