To pull this off, the team used procedural generation to create an entire universe inspired by the genre. Everything from the dirt, grass, trees and water, to the ships, the animals (and their sounds/behavior), and even the soundtrack is procedurally generated. If you don't know what procedural generation is, imagine Skyrim where you get to make your character in the beginning. All of the sliders to make your characters face and hair? No Man's Sky has a similar idea behind every feature, and the computer generates the outcome semi-randomly. But the sliders in NMS are math functions (or maths if you're from UK) and therefore able to generate much more unique combinations without becoming too repetitive (presumably). There are rules to this generation. A planet closer to a sun will likely be a desert planet, void of life. A planet too far from a sun, and it may be icy. The plants and animals on these planets are placed by the rules, too.
Yes, this is a game. There is gameplay. Many people are misinformed and think you just walk around passively and look at pretty things. That does sound very boring, and it could not be further from the truth. There will be times that are slower for you though. It's important you understand the game isn't "action, action, action!" like many AAA titles that we see. But there are things to do on your journey to the center... or wherever. You don't have to go to the center of the galaxy, but whether you want to or not, here's some things you do while surviving: Collecting resources, combining elements & crafting, upgrading your multitool, ship, and suit, trading with NPC's, bounty hunting, documenting everything you discover in an in-game encyclopedia, learning new languages, piecing together the lore of the universe, jumping through portals to unknown worlds leaving your ship behind, dogs fights in space, creating allies you can call to fight along with you, mining asteroids, jumping into hyperspace, rescuing defenseless convoys (or helping attack them), finding blue prints to new technologies, naming planets and animals, and honestly who knows what else? The developers said they are leaving many aspects for us to discover on our own. Your actions also follow you. When you attacked that trade route with a convoy of ships because you wanted their loot, guess what? You've made their wanted list and they might be hunting you in the future. So when people say "you can do anything", that's not true. What they mean is, you can play the game in a wide variety of styles. Be a pirate, bounty hunger, botanist, trader, explorer... or more? But when you hear 'you can do anything', think instead... there's no menu to choose what role you'll play. You just... go do it.
