This is basically what No Man's Sky did. When Bethesda took their crappy RPG engine and mocked up interplanetary travel using loading screens and then started writing quests and storylines, NMS focused on building a very good engine that allowed you to go from surface to air to space to interplanet / stellar while mostly ignoring the rest of gameplay and storytelling.

And not to be too hard on No Man's Sky given the resource differential, but ultimately all it is is one really rock solid system thats not quite a full game surrounded by a lot of hollow feeling stuff to kinda flesh it out on paper. Ultimately Starfield has way sharper hooks almost immediately simpy because while it has a relatively crappy engine and at time frustrating amounts of loading screens and limitations, they spent more time writing content and dialogue that makes the universe feel actually alive and rich, and polishing each individual system until it's fun.

I think The Outer Worlds is also worth comparing to as Obsidian is even farther down the same route as Bethesda imho, making a much smaller universe that feels even less free than Starfield but having even better writing and I would argue it's possibly the best game of the three though I have to withhold my judgement on Starfield until I atleast finish the main quests.
