It's pretty much exactly what I expected of it, and I can appreciate it for what it is. I do think the "hype train" went a little off the rails on it though, and many people are expecting more of it than what it is.
That being said, I pretty much seem to have started in the asshole of the universe.
My first planets/moons in my starting area are:
Frozen wasteland: Constantly refilling hazard protection due to extreme cold. Little life.
Toxic wasteland: Constantly refilling hazard protection due to extreme toxicity. Little life.
Irradiated wasteland: Constantly refilling hazard protection due to extreme radiation. Little life.
..?? Wasteland: I remember it saying something about low gravity (not noticeable difference on control, that I recall). For some reason this one puts extra strain on life support, so constantly refilling life support due to ..?? No life.
Wasteland: Pretty temperate, with no constant refilling of systems for protection/survival. No life.
I enjoyed Terraria and all, but that one was much more focused on the building from what I felt from it. A new planet on Terraria was so similar that I only spent a short time on a second planet before just going back to my original one.
With NMS, I feel like there's way more exploration than crafting going on here (even if the planets are kind of "samey", so far). This is kind of a perfect "chill-out" game for me (that's not to say the game itself if perfect, though). I mean, I am the kind of person who spent an hour climbing up a cliff in the first Tomb Raider game (underground pyramid area), not because there was anything up there, but just to see if I could. I also enjoyed (for the most part) exploring the planets in the first Mass Effect game. To me, those were more of a disappointment, especially now compared to NMS. They were handcrafted and not procedurally generated, yet gave you a very limited area to explore instead of the full planet and were all very lifeless rocky terrain from what I recall. So, at least in comparison to ME, this game is a strict upgrade to me in the exploration aspect.
As I hinted at above, it's definitely not without its faults, however. I've already ran into a couple or minor bugs with item placement - floating copper nodes, getting pointed to ruins that don't actually exist (stuck in the ground maybe?) - and one straight up game freeze. Also, it does seem kind of silly that Plant A on Planet X that looks extremely similar to Plant B on Planet Y are entirely separate discoveries. I do wish there were a little more diversity between the planets... but, with all my starting planets being wastelands with little to no life, maybe there will be some more diversity once I get out of this system.
