Will I be able to connect this resourse into my city network? It is my only source of copper. If I can't, I have a site for a new city picked out, but I would have to hurray as its away from my borders: Also, I have only been playing Civ IV for two days, but early game copper and iron pretty much are the same, correct? What about later? Are the two interchangable or should I ensure that I have both?
