Well, since players already assume they are running around with metal, lets say its the discovery of copper rather than the basic bronze. Also, since its a biggie (don't forget these can be traded/sold/stolen etc)
I'll charge it at 8EP.
I didn't think about this until just now, but bronze came after copper (copper is an ingredient in bronze). First you had the soft metals like copper and gold, then people figured that you could mix copper + tin to make bronze. Later people learned how to work with hard metals like iron, and then after that they mixed iron + carbon to make steel. (
Wiki)
So historically the order basically goes Copper -> Bronze -> Iron -> Steel.
Maybe instead of Metallurgy, we should call my research Bronze Working (or Iron Working, if everyone already has Bronze)?
I don't need any decision back soon (I'm researching it regardless of what it's called), but I thought I'd shoot you this so you could include the ruling in your update.
