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.
I enjoy it in Elder Scrolls Online. After "One Tamriel" the player can wander anywhere and complete content, both main and side stories, and the enemies and the gear they drop scale as the player goes.
I enjoy exploring that way and seeing what's out there. If I want to be challenged, there's trials and harder instanced content.
I literally came here to mention ESO. It feels nice to be able to take a level 1 or 200 character around and be able to complete the same number of questlines. I think it works for this game in particular because the worldbuilding details and the writing are superb and are the main reason I'm playing, so the game doesn't need any tedious grind and progression to make me keep playing. Those are just a bonus on top so you feel like your character is growing for all the work they're putting in.
loved ESO for the ~60 hours i played it. half of that time was spent in morrowind, i loved it so much. it just sucks how expensive it is. you either pay monthly or pay hundreds up front :(
