No Man's Sky is a cute early tier deployment of procedural generation, but not what I would call "good" in terms of gameplay.

Elite Dangerous is Mechwarrior In Space and cool as hell and I love it.

But hell, Eve Online has been a thing for nearly two decades. Star Wars and Star Trek have had multiple online multiplayer games. Then there's Warframe and Skyforge and Planetside and Destiny. Just take your pick. They all actually exist and are varying degrees of a good time.

You don't need to keep pining for Duke Nukem Forever In Space.
