Some of my favorite modpacks are Enigmatica 2: Expert, Omnifactory, and one I just started recently, Divine Journey 2.
They all have a similar process of starting with nothing but a book full of quests to guide your progression, and end up with you automating everything from farms to quarries to mob grinders in order to produce items that have comically difficult "recipes" to craft.
Scratches the same itch as Factorio, Zachtronics games, Satisfactory, etc. but often has some fun side goals such as making your factory look beautiful, exploration, fighting bosses, and best of all, getting your friends hooked on the game and playing on a server in a group!
