I agree, its not really integral for an RPG. Bethesda sees it the same way.
Its naturally in NMS because the whole game is procedurally done and landing and flying was in there from the start design wise. Most tech demos for procedurally done space start that way (Youtube is full of them).
I always liked it in Frontier, starting from New York and flying directly to space was awesome and absolutely mindblowing on the Amiga. And you could always land with the landing computer if you didn’t like this stuff. But Frontier is a real space sim, Starfield and No Mans Sky are not.
