It's not skepticism, that would imply that there was already some kind of possibility of it actually happening and we just don't believe it. The fact is, adding new games to GOG is not only so unlikely as to be a virtual certainty never to happen, its something that would go against what the site was established for in the first place, which was to provide a place to legally obtain those old and impossible to find titles we want without the hassles of DRM, configured to work with modern OSes and hardware and for a reasonable price. How would selling new games here fit into that in the slightest?

I have been thinking that they could chage the name (or setup a new site) to GG (Good Games) where it would be focused on DRM-free Indie games.
It wouldn't have to be limited to Indie but it would be a great start. :)

No.
Most GOG games are already newer than I like as it is.
