Previously in the closed alpha stages of testing with the help of thousands of gamers, GOG Galaxy is an online platform that features one-click installation and auto-updates for its library of over 1000 titles, but it also stays true to GOG.com values: it is all optional. Automatic updating can be disabled for any game; but if you leave it on and a patch breaks something, GOG Galaxy will offer its rollback feature to restore a previous version of the game. Gamers can also download a standalone, DRM-free backup copy of every game.
GOG Galaxy offers friends list, game time tracking, achievements, and chat. Gamers can now talk to each other, connect with their group of friends, and see what their friends are playing. GOG Galaxy is also an online multiplayer & matchmaking solution that, in select titles, includes cross-play: platform-independent multiplayer between gamers on GOG.com and Steam.
