No Man's Sky was released 7 years ago yesterday (August 9th) on PS4 in North America, today (August 10th) on PS4 in Europe, and August 12th on Steam.
How long have you been playing and how many hours have you played?
I started around Beyond (2.0) and have almost 3800 hours played.
Who is the someone NPC?
Nope, random rich players like myself, with more goods and money than brains lol. Although some of the updates added some very high price items, so last time I played, I made a pretty good dent in my riches.
So players can see one another now?
Oh ya, the hub is where all players can get together and group up.
Cool may start playing again.
You're talking about the Nexus aka Space Anomaly - "the Hub" usually refers to the Galactic Hub, which is a player-made, developer-canonized community.
