Isn't Mincecraft basically that? I've never played it, so would be curious to hear from someone who's played both. From the outside both look very dull/soulless and yet people spend hours playing Minecraft building things - just engaging with their imaginations
Building in Minecraft is a very different beast than building in NMS though. The prebuilt cabins and machines of NMS aren't the rabbit hole of redstone engineering that Minecraft has.
Basic Minecraft is basically that imo
Modded Minecraft is a very different beast, depending on the mods
It's pretty cool to see what modders have done with it over the years. I genuinely think Minecraft + Create is the best factory game.
I think one thing that Minecraft does very well is that it does not push the player towards any of its game systems, which allows the player to make up their own fun. No Man's Sky on the other hand throws a lot of different game systems at you. Just having points of interests pushes the player into just going from one to the other instead of them exploring what might make the game fun for them.
