It's weird that you would do all that math without thinking that groups of people will probably be spawning close together, and that we'll be able to warp to popular planets/places. I don't think the dev is going to overlook something like that.

if everything is how they said/how i understand it you wont. how many sytems/space stations are there? I doubt you can imagine the size of a complete galaxy with 18 quadrillion stars.

They said it will take a single player 5 billion years to visit each planet if he visit a different planet every second.

So if 5 billion people will play the game (thats almost the whole world population and very very unrealistic) and everybody would visit each seconds another planet, it would still take 1 year till each planet got visited ONCE. No sleep, no food, no not gaming in the full year for 5 billion people to visit each planet ONE SECOND.

The conclusion i get from this is, that 99,9+% of all planets in no mans sky will NEVER be visited by any humans at all. It will never happen, even with a 50mio people playerbase.

If we have 50 mio player and each player will play the game 100 hours average and visit 10 planets per hour, each player would visit 1000 planets at all. 

That would be 50.000.000.000 planets at all ever visited liftetime.

18,446,744,073,709,551,616 - 50.000.000.000 = ~ 18,446,744,068,709,551,616 planets that will NEVER be visited at all.

they said everybody will have their own spawnpoint. And what is "close" to you? You wouldnt even meet if would spawn on the same planet.

All people really cant imagine the real sizes of the game. I do understand that, this are some really big numbers most people never heard before and cant handle.

The said nothing about warping to other people though.

Trust me, if you want to be found it'll become much easier to find you on these planets... If me and my friend set out in this game with the goal of meeting up, I'm sure there would be a way to do it without having to randomly go through every planet there is... Sure, it might take some work, but I bet it would be achieavable if you worked a bit, even without spending ages.

only if they gave you and tools to make it. Otherwhise nah. Way to many planets with way to big sizes to make it possible.

Another example.

You will need ~100 hours to read the center of the universe (they said). If you friend would theoereitcally spawned at the other size of the universe (it will be a circle), you would beed 200 hours to at least get there.

Even if he isnt spawne don the other side, 20-30 hours travelling will be realistic.

What would concern me is the amount of planets and the amount of data that they'll need to store for every creature/record etc.... it just seems impossible.

Cant wait to give it a go

it wont be stored. Everything will be generated using alot confusing mathematics^^.

And if you will get anywhere again, it will be genereated exactly the same again (it will use some constants to calculate everything).

So theoretically the universe only exist, as long a player is there.

There are co-op mechanics confirmed so we'll see how that works out.

Yeah in the 18 minute gameplay sean said that on the planets you can legit walk for hours and hours and hours in one direction

That's assuming that every planet and direction you go to is completely random, which it's not.
