Galaxy now works just like Steam. Developers can use it to upload game patches directly to their games. It works really well. I haven't manually With BG3, I got all the patches on the same day as the Gog release. I wish all devs would use Gog, but since Gog has an official stance against DRM, developers often stick with Steam. At any rate, Steam sort of shot itself in the foot with that announcement. Yes, games are licensed, but what they neglected to mention is that the license includes a copy that runs on your hardware...;) If it didn't, we'd get a license to nothing. Copyright law even allows for an archival copy! I prefer Gog not only because of their DRM stance, but because of the fact that Gog gives you your own installable copy, which Steam does not. I use Galaxy to update my games because it's so much faster and easier; but when the developer is through issuing patches, I download the manual Offline installer for my copy. Plus, every game Gog sells can be run from its own executable, bypassing Galaxy entirely.
It is well known that I cannot err--and so, if you should happen across an error in anything I have written you can be absolutely sure that *I* did not write it!...;)
