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.
If you count rouge likes, Risk of Rain, FTL, and Dome Keeper all scale well. The last one scales in a weird way that as you unlock more play styles, you get new enemies. And because each play style is unlocked by clearing a stage, it means you got better so the new enemy will add variation to your next playthrough.
