It’s easier to make small saves for games like The Pedestrian, because essentially all you have to track is which puzzles you’ve solved.
Whereas in an RPG with a persistent world like Cyberpunk or Skyrim, you have to save the state of every single object and mechanic the player has interacted with during their run, and there are usually a whole lot of those.
If you want to own your games, buy them on GOG.
