So, you know how the pitch here is that there are billions of different worlds in No Mans Sky? You could play forever and never see them all. OK, fine, neat trick, but there's a remarkable amount of "sameness" to every planet.
I have done literally no research on how NMS, specifically, works, but I think I understand how they make a game with billions of worlds, based on my understanding of procedural generation in games (an area I like to read about, but never actually do anything with). 2/?
