With gog? of course i can. I have the files and i can give them to my family. They can then play them.
The fact that I'm "buying" a license holds as much weight in this issue as the countless eulas and privacy policies i supposedly agreed to.
We "endusers" live in a world were we are compelled, yes compelled, to enter legal agreements to do anything, and where these terms are dictated and changed unilaterally. Terms like these should and are meaningless yo everyone except for courts that foolishly hold them valid. For everything else, they should and are ignored.
