Basically Starbound at triple the cost and a third of the level of interaction (not counting the modability that SB has), from what I've seen. Progression feels more like getting shit to do the same shit for longer without much shit changing other than getting more capacity to do the same shit you've done from the start.
Considering the fact that the upgrading aspect is just another number vs. number game (damage numbers against opponent x, increased timers to remain on planet y for longer, number of the amount of shit you can take after mugging faction / territory z) it pales in comparison to other sci-fi's, including the underwhelming Star Citizen.. In SC, getting larger ships allowed you to become a trader, while getting other smaller ships made you decent at PKing or running as security. These changed your style of play, each with its own intricacies and so on. In SB, new tech meant you could explore places you could never before, which in turn opened up to different mechanics of the game, like building, combat, or trying to master the redstone equivalent. You had different styles of play, each with their own little intricacies.
Hell, even Warframe had some level of intricacy even though 100% of the mechanics were dedicated to you killing more for longer. Companions automated shit for you to do, pubescent psychic children could help you bypass shit that would normally cripple your happy time, and the time in space you were allowed to go into could be spent racing through a level like a ping-pong ball in the most violent game of space-connect-the-dots. Or be a tie-fighter (two entirely different experiences, though both will make you vomit from the lack of any reference as to what is up or down)
At it's core, the game (NMS) is more or less meant to be played at its most basic form : exploration and little hikes. Evidently, there isn't much else to do, and every advance you make in the game is just for furthering that purpose.
Point is to be Tom Cruise in Cloud Atlas.
