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.
You don't need to manage the exe files. Just install heroic launcher. You can access and install your whole GOG library from there, and you can configure each game with different versions of wine or proton, if you need to. It also integrates with Epic and you can easily add games to Steam as well if needed.
You can even sync the game saves with the GOG cloud, although last time I tried the save sync was a bit clunky.
Yeah I've used heroic launcher, but a native launcher is still preferred. I like the GOG launcher on windows.
