I just realized that other than Skyrim, every western RPG I've actually enjoyed has a protagonist with amnesia of some kind (Planescape: Torment, Disco Elysium, Knights of the Old Republic, Morrowind)
what this tells me is that it's nearly impossible to create a compelling RPG without making the main character have an actual backstory
western RPGs are so heavily influenced by D&D that they can't imagine not letting you create a character from scratch, but the thing that makes this work in real D&D is the way the DM puts a lot of work into making your character choices matter to the game, and afaict no one has figured out how to Do This With Computer
