I can’t think of a single game that manages to have enemies correspond to your level rather than area or story progression actually contribute to the game. It just makes trying to get better gear ultimately a pointless task because the enemies get strong at the same rate so you might as well stay weak.
Someone already mentioned Breath of the Wild, that game does it pretty well. Best example I can think of is Alien Isolation, where the AI actually just gets smarter and more resourceful as you unlock new skills and items.
