Morrowind didn’t have much, if any, enemy scaling. Which is fun when you’re at low levels and trying to avoid caves full of high level enemies but can make things dull if you power level.
This is a good thing, it means your accomplishments and growth are meaningful and impactful. Nothing worse than becoming some godly powerful being and yet everyone else in the world suddenly is godly powerful also, makes you wonder what the whole point of leveling is. In Morrowind once you are able to take down high level opponents, you feel like a badass and you know it. You truly achieve godhood. The expansions also are more difficult so it's not until very late game that you finally get strong enough not to be challenged (unless you exploit of course).
I actually like that kind of scaling in RPGs where you start out as powerless but become overpowered towards the end - Mage classes often tend to scale like that.
