I say we should add material energy natural capital its a lot like factorio and fortress craft evolved Overview - Material Energy^Natural Capital - Modpacks - Projects - Minecraft CurseForge
Actually this pack is not really for single player, unless you are referring to the amount of lag it can create if people start to automate stuff. But how is that different from other packs? Natural Capital is a open world pack heavily based around tech and automation. It has a hqm book, which guides you a bit through the pack. I know that Parcel abandoned this pack and someone else took over. Last time I checked the quest lines weren't really finished. It has some nice features though, especially the fact that wood and water is a finite resource. It also comes with a customized world and oregen.
from what ive been playing of the latest version only a couple quests are broken that is like 4 out of all of them and in the newest update one was just fixed and a whole bunch of problems are fixed
