GOG Galaxy is already a very useful platform, combining disparate stores and their libraries into one large game cupboard; games can be downloaded and launched from GOG Galaxy, and play times and achievements are also tracked. Starting today, at least some testers can also purchase games from other stores.

Previously, GOG Galaxy's store tab only included GOG's catalog of games, but testers can now view select Epic Game Store Exclusive games can now also be viewed.

In addition to the convenience of not having to travel back and forth between stores, purchasing games on GOG Galaxy is also subject to GOG's rather generous refund policy: on the Epic Games Store, you have 14 days to request a refund, and only if you have played less than two hours. GOG, however, has a 30-day policy, regardless of play time.

You should check your inbox as invitations are sent out. More games and features will be added to the store, and presumably GOG wants to do this for all platforms they support.
