Would that make a superior game? Perhaps some people consider this analogy unfair since SMB is mainly a linear game. Experienced players who have poured hours into the game should not have much easier of a time completing stage one as opposed to completing the final stage of the game. So if we apply this level scaling mindset that the challenge of the game should be relatively constant throughout, the first stage should not be considerably easier than the final stage of the game. In all SMB games starting with the first on Famicom/NES, the first stage was always exponentially easier than the final stage in which you fight Bowser and save Princess Toadstool.
Let's consider the idea that a game which doesn't have a relatively constant difficulty throughout is broken and in need of a fix. I also question the mindset behind it - that any game, open-world RPG or not, should have a relatively constant difficulty throughout the entire game (never too easy, never too hard). There's no game mechanic I despise more than level scaling.
