Great news :D
"GOG Galaxy, our gamer-friendly Client, is coming out of beta with a major new update that greatly improves and enriches the user experience with the introduction of many long-awaited features. Let's take a closer look at some of them:
The highlight of Update 1.2 is, of course, the Universal Cloud Saves. This new feature makes it possible to add cloud saving functionality not only to new games, but also to titles that never offered cloud saving before. Thanks to this, excellent games like Planescape: Torment, Heroes of Might & Magic® III, or
Vampire®: the Masquerade - Bloodlines gain the benefits of saves syncing and cloud backup for the first time ever. Of course, if you prefer to keep your precious saves close at hand, GOG Galaxy also lets you download a backup of your saves data at any time and use it as you see fit."
