In usual recipe I make 16 rails from 6 pieces of steel. It's very expensive to build long railways. I want to change recipe - instead of 16 rails I want to receive... for example, 160 rails. It'll be much easier to build rails, comprende?
make a chainmail crafting mod. and add plated armor that is stronger than their vanilla counter parts. and maybe a snowglobe mod that displays the weather the biome it is in ( kind of an aesthetic thing).
