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.
This is a future proofing measure. With the enshittification of Windows there is a reasonably sizable share that is looking to migrate. Making an API/front end functional on the platform is just good business. I for one will be switching 95% to Linux the instant Microsoft acts on their patant for putting a mandatory advertising ticket on the screen. Literally the only thing I will use it for is programming things for work.
