PC game distribution service GOG.com announced a DRM-free, Steam-like client called Galaxy during the CD Projekt Red and GOG.com Summer Conference livestream today. Galaxy allows players to access their game libraries, earn achievements and can be used to connect with others for multiplayer gaming action.
The client will offer cross-platform support for those playing online with others that are using other clients, such as Steam. It's also totally optional: Those looking to just play their games offline won't need to use the client. While Galaxy will not require any online activation and will handle game downloads and updates, players won't need to use the client if they choose to do those things manually.
Update: GOG.com issued the trailer from today's presentation explaining the Galaxy client.
