timppu: From my point of view, the amount of games that could reasonably be expected to be "GOG exclusives" is going to be thinner and thinner, so it is not reasonable to expect GOG to sell only "unique" games that publishers think will not sell elsewhere, or other stores are not interested in selling.
Klumpen0815: Like
Hovertank 3D which they actually rejected?
https://www.youtube.com/watch?v=P7juV9zo5Tk If that is an example of potential "GOG exclusives". then we are all doomed. :D I get sleepy by just watching that game, let alone playing it. YMMV, but I don't see games like that being the savior of GOG. Not sure if it even has any historical value, unlike Akalabeth which is offered as a freebie.
(Good thing though that I checked the Youtube. I always thought Hovertank 3D was another game, namely I recall certain early Windows (WinG?) game which I think was also about hover tanks in a 3D environment. I don't recall if it came with Windows 95, or if it was available already for Windows 3.x.)
EDIT: Oh right, it was "Hover!", which apparently came with the Windows 95 installation CD:

Oh right, it can apparently be played online as well through a web browser:
