I really don't understand the DA process for negotiating treaties with the AI's. When I open the Relations screen and click on an AI, sometimes my screen shows Research Treaty or Economic Treaty, one or the other, sometimes both, sometimes on my side, sometimes on the AI side, with no apparent rhyme or reason. I've checked to see if my relations with a given AI have anything to do with it and found that it seems to be just as random even if I have a warm or close relationship with the AI, or even if I have already another treaty with that AI. In yesterday's game, I negotiated two treaties as the game went on. Then I went through the diplomatic techs all the way to Total Majesty and still couldn't get an opening for some more treaties I wanted to negotiate. I don't mean I was turned down, I couldn't even offer to make the treaties I wanted because the screen didn't have the treaties listed as assets for either me or the AI, one or the other, again with no apparent reason or system. So it wasn't that I didn't have the diplomatic tech and skill to make a treaty, and it wasn't that I didn't have a good enough relationship with the AI. So what gives? It's hard to believe that the game makes the ability to make a treaty completely random. Can someone help me out here?
Thanks for your replies.
