If they ever do get around to a Starfield survival mode, I think it will break people. I can't imagine how difficult it would be to actually have to establish bases on specific moons just to mine helium for fuel, then plan your system jumps for quests around what resources you have to even make it back. Let alone food. Let alone getting radiation or temperature damage if you're outside your base for 5 minutes. Imagine if they made oxygen a resource too. And yet, it feels like the whole game was built for that.
I'll have to try Fallout in survival mode.
