Gaming

I don't even think it's that. Lots of RPGs have had "do X more to level up X", including old Bethesda games, but it's riddled with problems, which is why most games don't do it anymore. As for level scaling, at least they finally got rid of that, but the way they guide you through the galaxy in line with your level involves basically being equally far along in each faction quest line at the same time instead of having low level factions and high level factions.
