I am at turn 137 of my first attempt at Apollo level. My neighbors are ARC and KP. I had worked hard to get ahead of the Russian in science. Granted, I was behind the others by a couple levels of affinity, but I was COUNTING on my "alliance" with KP to help if ARC declared on me. They were about equal in military. KP was one level ahead of her in affinity, I believe. So, ARC declared on me, and as far as I can tell, KP just sat back and did ZERO to help. I don't think either of them crossed a border. I have been slugging it out with ARC in a stalemate for about 20 turns. Oh, and to add injury to insult, KP just made "peace" with ARC. So, can somebody explain to me how this so-called "alliance" works? It is like "favors". That is, almost meaningless (seems to me). The diplomacy function in this damn game is terrible compared to CIV4 (where I came from).
