GOG GALAXY is a fully optional client to install, play, and update your games. It also offers online multiplayer, achievements, chat, game-time tracking and more - but it’s up to you which features you want to use. For all games, you can download a DRM-free backup installer that you can save to an external disk, drive or cloud. It’s up to you when and how to play your games. GOG Galaxy will always work without an internet connection, and so will your games. Add people you like to your friends list. With a single click you will see if they’re online, what are they playing, start a new chat or invite them to a game.
