I have never had an experience made worse by save scumming. I have frequently had an experience made better, or a game made tolerable at all, by save scumming.

The game I save scum the hardest is Rimworld, because it’s made to be a tragicomic story generator but I like to play it as a happy commune builder. Rimworld pretty much always has a way to fail forward, it’ll send more colonists whenever you’re running low, but it would be absolutely unplayable for me if the designer had thought that meant it didn’t need saves.
