Hi,

I just discovered Gog Galaxy and I was wondering how DRM free work for Gog Galaxy users.

I would like to test the beta multiplayer with two friends of mine, it is possible with only a single purchase of Stardew
Valley (described as DRM free)

We intend to play the game on Lan only ( offline if possible )

If you plan on just using the LAN option, that will work with or without Galaxy. My brother and I have been sharing the same copy over LAN with just the basic IP connection process.

You only should need multiple copies and Galaxy if you want to use the Invite Code option.
