Yes. And this description gives me Alone in the Dark (2007) vibes: they explicitly stylized chapters and subchapters as episodes on dvd. Would they make something original to build a game around this idea? Would it be linear-only, for games like TLOU with limited choices? Or it's just about patenting everything that's not nailed down?

I think it would only stand out if you would be able to rewind and passively watch the in-engine recording of your whole previous gameplay (like in cybersports, or clip editors in some games), with an option to jump in at some sections. But it's a little too much to implement smoothly, having no reason.
