I'm sure this exists somewhere but I tried searching and the only thing I could find was a sample game that didn't really explain diplo at all. Can anybody point me to something that explains the consequences/costs/benefits of various diplo options? I really have no idea what is going on. For example, if a Civ says I have units near their borders my options are to immediately declare war, or to tell them it's all good. But that option doesn't stop me from declaring war. So what's the downside? What about when they warn me not to settle cities? Thanks in advance.
