OK, so I just moved from emperor to immortal level and its becoming a bit tricky to me. The main problem is that I somehow manage to piss off all my neighbours way too soon :(
The only obvious diplomatic option to keep good relations is a pact of cooperation. But do such things as trade and research agreements or open border treaties make actual impact on your relations? If so, what are their relative values? Also, apparently giving money to other civs should make them happy, but how much should I give to make any impact?
In Civ 5 (unlike in civ 4, where it was clearly identified positive or negative points for diplomatic relations) it all is very vague, basically what you have to do is read the leaders body language. Which I think actually is very realistic. So the only two ways I can think of answering this question is:
- to try and dig in some modding options, like some default values is some .xml files or anything, does the modding affect diplomacy at all?
- to share your experience.
So I shall share my experience in my own answer.
