Let's keep in touch!
GOG Galaxy comes as GOG.com’s desktop client designed to help users keep their games sorted and updated. You can even choose to roll back any of your games to a previous version.
The latest Galaxy 2.0 update transforms the client into a unique service that gives you the chance to connect to other platforms and brings all your games and friends together in one place, so you can chat through instant messaging.
As for this special cross-platform friends list, note that it even lets you see the online status of members across connected PC and console platforms, as well as the titles they are playing.
