To those malding 5stars that scream 'but it's a website!' - that doesn't matter. Anything you buy on GOG you should be able to keep forever and use without an internet connection. That's the whole point. And if you had a breath of intellect, you'd realize it's entirely possible to ship a website as a locally launched tool. The fact that all you're buying here is a key is literally DRM, no different than Steam.
