I have no problem in giving away Assembly line if I feel I make some good business. Sometimes a +1 diplo is of much higher value than a tech. Also, you give an extreme example: aren't you pleased when the AI comes threatening you into giving him, I don't know, theatre ?
Drama, you mean ? No, I dont like giving anything because it lets other AIs become more advanced ("i fear you become too advanced"), so they'll become more powerful, which means I'll be the target anyways in the future. I cant demand anything higher than 300 beakers at marathon speed (they wont give it to me even if I'm 10000 times stronger than them), but they keep demanding everything from me every turn, even if it costs 21000 beakers, that's ridiculous.
As for your other example, I also fear it is a little bit extreme; I mean, you search for it: on a small map with 18 civ, for sure you will have more leaders asking stuff from you (there are more of them), and for sure someone will DOW you one time or another (there is no space);
Yes, there are more of them and yes, someone will DoW on on me, i have no problem with that. The whole point you miss is that they dont ask anything from each other, so they'll stay easily pleased with everyone, but not me. So, I'm always the main target, instead of just part of the world.
also, wouldn't you do the same if you have no space to expand ? And when an AI DOWs an other one and you had plan to DOW on of the two, won't you do so?
Yes, I do, but not always. I like to roleplay sometimes.
And when an AI asks you "please come help me", Do you always send stacks to indeed help him like you would expect them to help you when you are attacked?
I still don't see any problem with "anti-human bias".
Problem is they can ask for help when I'm already at war, but I can't if they are. They also don't ask for other AIs to help in their wars if that AIs are already at war. I'll take a screenshot next time, so you'll see what I'm talking about.
Problem is it cannot. You will never act the same way as the AI does, and it will never have the same level of intelligence as you which permits you to avoid DOWs and make friends. The difference in behaviour is something necessary. Otherwise, it would be too easy for the human to manipulate politics.
Or perhaps you would be glad to have an AI which acts as humans do? DOW at friendly without any warning just because "you are in my way" ? Speaking for myself, I don't. And I am sure lots of players feel the same way.
So, let's just get rid of the diplomacy system. Diplomacy was always more important than wars, but it's not true in game. I could explain better if my english wasn't so poor, but diplomacy system could be much better. For example, human or AI player Dow on friendly should get a huge negative modifier from ALL players. Can you imagine USA DoW on UK while the world thinks that's the same as USA DoW on Iraq ? Chile Dow on Brasil because they didnt give advanced flight to them ? Anyways, I could live with that in game if AI just did the same with each other.
Back to OP topic: AI bias against the human is necessary. If they treated us same as each other we could reel off ridiculous easy UN wins using "peaceweights", have perfect diplo constantly, and not responding as they do now to our demands.
True. I usually turn off diplomatic victory, but I know it could be exploitable. IMO, the whole diplomacy system should be revamped. Making friends should be more than just accepting every demands. Maybe a diplomacy bar, I dont know. I agree that tributes are part of the game, but it should not be the diplomacy core, only a payment for protection. Civ IV is almost perfect to me, it would be if diplomacy and espionage systems change (now I turn espionage off).
A lot of this is just experience - the more a player has, the less the AI feels "biased" against us...although the annoyance related to incessant demands never does go away unless you force that civ to exit stage right
.
I dont like to feel obligated to get rid of every AI just to see them stop being so annoying. Sometimes I dont even want to win, I can have fun in a multipolar game I'm not the strongest, but I have friends, that's why I play with 18 civs in higher difficulties. However it's not always possible because that "friends" wont help me if they are already at war or if they are friendly with my enemies, although I get negative modifiers for trading with their enemies.
