no man's sky looks boring because it misses out on all the boring stuff.
you can actually do far less in elite. you can't land on a planet and go swimming in the reeds with dildo monsters or anything, but what it understands is fidelity. everything you can do is wrapped up like an onion of increasingly particular and spergy detail, the galaxy map alone is like a proper piece of functioning software.
NMS just kind of glazes over the details "you can fight giant spaceships, study giant strange animals, you can go anywhere", but everything is done on such a shallow surface level that none of it has any value.
it's like the difference between shooting down a few bogeys in ace combat and adjusting the trim or whatever the fuck to get a kill in dad's rivet accurate grognard flight sim: 1942
