GregTech, created by GregoriusT, is a Mod that completely overhauls Minecraft, adding numerous Machines and Materials, as well as adjusting Recipes for existing Items in order to make them fit with its System. GregTech is meant to extend the Game by making things much less overpowered, more reasonable, and adding a lot of complex machines, as well as generally useful utility.
