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.
I wouldn’t mind supporting them if they could provide a Linux tool that let me download my library in bulk.
The best you’ll get is Heroic Games Launcher. It’s got most of the features I’d want at this point.
