Many games on GOG are at the tail end of their sales cycle (i.e. were released on Steam long ago) trying to eke out a few more sales, are from small indies for whom any attention at all is good attention, or are very old^H^H^Hclassic games that garner purchases for nostalgia's sake by older gamers that can afford more discretionary spending.

And many aren’t.

I bought Factorio early access on Gog, and Timberborn, and Loop-Hero.
