Quests! Enigmatica 2: Light has over 800 quests, that help you get into different mods.
The pack offers over 200 different mods, such as Thermal Expansion, Tinkers' Construct, Mekanism, Thaumcraft, Astral Sorcery & Immersive Engineering.
The pack aims to have everything as balanced as possible, without gating. Power generation has been tweaked heavily, so generators that aren't usually worth the effort, might be in this pack. IndustrialCraft2 EU can be converted to RF, and vice versa, with Mekanism.
A ton of new dimensions to discover and explore, and the ability to create your own!
