Luna is Amazon's version of cloud gaming that's newer than the services from Nvidia and Microsoft, and may have an advantage if you want to use a Fire tablet or TV, or want to use GoG games you already own [some GoG games are supported on Nvidia's GeForce NOW].
On Luna you’ll be able to play every game that you already own on GOG (and that is also available on Luna). There’s absolutely no requirement to purchase anything twice – you bought it once on our platform so it’s always yours, as always.Moreover, it works both ways. You’ll be able to buy games that are available on GOG via Luna’s client and they will go straight into your GOG library.
In other words, buying games on GOG (directly on our service or via Luna) will give you the best of both worlds – enjoying them on Luna’s cloud gaming service, as well as via offline installers or GOG GALAXY. All your DRM-free benefits of owning games on GOG will still be there, you’ll just have more ways to play your favorite titles.
And of course features of GOG GALAXY such as cloud saves and achievements will still work when playing on Luna – don’t worry about splitting your progress.
