I mean, the only thing that’s really needed is the standard access to the creation kit. After that, I think modders can polish it up to competency, although flying to planets might be outside the abilities of the engine. I think anyone still hoping Starfield is going to be a good space game need to stop dreaming and go back to Elite/No Mans Sky/Waiting for Star Citizen, but there were some really elaborate mods for New Vegas and Skyrim back in the day. Maybe someone dedicated and talented enough could even fix that.
