And the steam stats for it - https://steamdb.info/app/275850/charts/#6m

As I write this, there are 10,467 people playing it now. (The stats from 2017 where in the 1000 - 2000 players playing it).

Comparing it to Factorio (which is a great game) it has 19,103 players playing it now.

As a person on the far side of my 40s, No Man's Sky occasionally gets dusted off for some play.
