I see what you’re getting at, I could see how someone might assume an seamless outer space based on that. As soon as you realize how much of a technical undertaking that is though, it’s easy to assume they wouldn’t go that route and not have blown that horn 2+ years ago as a huge feature. Something like that combined with a BGS RPG would be massive and I can’t imagine a world where a company like BGS or Microsoft would be wanting to keep that a secret until release.
Funny you say that, Daggerfall is fondly remembered but only in spite of it’s procedurally generated overworld. Daggerfall’s openworld is extraordinarily barren, remarkably so. You literally will get lost if you walk more than 5 minutes from a town, and not in a fun way but because every direction you look is literally the exact same three tree and rock sprites and you lose sense of direction. Daggerfall’s overworld is so bare and empty and large it actively encourages you to engage in the fast travel system with fleshed out gameplay mechanics like camping supplies and vehicles.
