Create is a mod for Minecraft. It is more or less a three dimensional version of the popular game Factorio and it combines Factorio’s automation with Minecraft’s creativity, plus a variety of moving block-built structures. It is the most impressive mod I’ve ever seen.
In Summer of 2022 a friend set up a server with this mod and it ran for about a month. I became quite addicted and created my most elaborate modded base yet. Called Diblandica (as is traditional), it was themed as a steam-age mining village. It eventually grew to occupy most of a good-sized island.
For my later efforts with Create, see Create 3.
