The Witcher 3 has a new trailer and release date, but perhaps the biggest news to come out of CD Projekt RED's Summer Conference event was the announcement of sister company GOG.com's new platform, GOG Galaxy.

Sticking to the company's DRM-free mantra, GOG Galaxy will function as a completely optional client for games on GOG, which will all remain otherwise directly downloadable from the GOG site, and will still permit the single-player component of any GOG.com games to be played offline with no authentication services required.

What it will do is provide a services layer for supported games that do have a multiplayer component, and claims that it will be cross-compatible with supported multiplayer games that are purchased via other platforms such as Steam.

The first game that will support and roadtest the new GOG Galaxy service is the freshly announced The Witcher Adventure Game, a digital boardgame title that CDP will be running a closed multiplayer beta for in the coming months.
