The Elder Scrolls Series has had level scaling from the very beginning in Elder Scrolls 1: The Arena, it became more pronounced with Daggerfall, more subtle with Morrowind, but it was still in Morrowind, Oblivion put it on full display, and Skyrim over-tuned the player to compensate for it.
I'm not actually saying it's a problem, but people tell me it is, and that's an interesting topic so let's talk about it.
