While I don't believe the PS5 has any feature that is up to snuff with quick resume, just wanted to mention that I think this feature was a bit different in function. It was more like a shortcut to specific things within a game, such as if you wanted to just go straight into a multiplayer match or to a specific level of a game, you'd use one of these activity cards, the game boots up, and there'd be minimal to no menus to navigate through. Just launch direct to gameplay or as close to it as possible.
I don't believe many games used it, though. Not even all of Sony's own offerings.
