Oh, surely GoG have lots and lots of drm-free games. It is big part of store, mentioned in ads and many interviews. They actively providing more and more drm-free, probably even silently cheer up SKG (even if avoiding saying this loud).

My point was, not every single game on Gog store is drm-free.

Guess You mean GoG, they do offer most games as fully downloadable installer and most licences fully allows You to keep them forever, even if servers and services of Gog goes down. Not all of them, as they also offer games with separate launchers and stuff. Some games may be online only, like mmo genre, not much to do here, even if You manage to get all files stored. There’s always chance publisher takes the game off the store, or there may be some legal issues. Gog still trying to provide fully offline installers as much as possible, or even provide own, (semi) unofficial patches to old games to make them run smoothly on new operating systems (not intended to by original devs).

Much awesome, even if cannot say all games DRM free.

Yes, yet they do respect that licence and customers… so far, we trust them mostly.

Once day, Steam may be gone from market, replace by another service, who knows, and our libraries be gone by turning servers down - there is a possibility. But I struggle to imagine Steam would delet a game from my purchases without refunds and without any really serious reason, like few others do.

May depends on place, but I believe most of globe is fairly easy to avoid nestle, even with cheaper alternatives.

For games, until following most famous games, theres lot of alternatives to aaaa games, that are often way clearer of bugs on release date, often cheaper, and don’t require 5090 to work on medium details in 1080p. Few games like gta-clone, sims-like or diablo-like may be unique on their own, it would be even hard to ignore them in social/popculture aspect, so many gonna compare everything to few biggest. Still it is about paying them lot, preorders or throwing monies at worthless dlc day1 horse armors… We can ez avoid lot of that.
