A retro-style modpack based on mods such as BuildCraft, IndustrialCraft 2 Classic, and Project Red. It also includes at least one character progression mod to incorporate adventure and RPG elements.
This mod is heavily inspired by Aroma's mod. It allows you to create a dimension for ore mining—just in case. It is particularly useful when, for example, the Overworld has been heavily altered by other mods.
Crystal's Additions is a mod that transforms Minecraft into an adventure-RPG with a character progression system. It also completely overhauls the overworld's biome system and provides new reasons for exploration.
