You ever hear the complaint The AI's in civ3 can be bought up and influenced to go to war with the strongest civs for the price of a bag of beans? I know Smidleee like to say this (to lazy to quote)
I never believed this mybe cuz I played CIv3.5 ala mod alot but check this out.
Freaking Serbs are a lil powerhouse and in the vacinity of my enemy but won't get their hands dirty without me breaking the bank or giving thousands up in research commitments while they go an military spending spree! . IN the next pic You'll see They want all of my money plus the freshest tech on the market! WHat happened to the bag of beans theory? IM better of doing the diry deeds myslef, atleast my units get the promos
Here they are this time asked to go war against Germany, the number 3 ranked powerhouse
I started using prt screen every time I found this 'fact' to be untrue Now I have a vault of these AI being crafty and I don't know why or how to explain all these smart diplo calls.
I was hoping for prices based on CIv4 complainer's remarks.
Now remember I have to bribe a coalition to be effective in my goals since mega map means mega sized opponents. Whats this cost me in the end? HOw about THe science race to some fat civ that sits untouched after dominating the other side of the world.
Its because of over zealous tech trading you enemy can whined up with
near same tech level plus, still could afford army production that doubles yours and which let them conquer half the world. EX LIke this...:
They simply called me out early and I had to pay all the civs close to me to stay on side. Otherwise what happens? He sends them after me! Think what trouble that would be! Look for yourself on the
Real WORLD MAP SIZE! my sprawlin empire's HQ is orangy red upper left OK, Now I got my neighbours going against him bad thing though is they will have to settle some day and guess what? Hes bigger so they pay! MOre cash and techs go his way! SO People who say we are master manipulaters in CIv3, mind telling me How this always comes into play?
IS it cuz of my rep? Well some civs will still except my offering even with a rep hit or two. They then take my tech, fight a bit with the allience who I also paid steep for, with thier help they take some land for themselves then they pass on that tech to the enemy to stop from gettin clobbered in counter.
NOw my enemy has better techs and cleaned out his outdated units to roll in the power units (means better value maint price) for when I decide to come in!
So How munipulative was that for my side? How would you have done it? Remember Armies have been
patched! 
SOmetimes I notice the civ that can't be bought cheap
is needing a resource that the proposed enemy is suppling them.
I also notice the army strenght in realtion to each other is measured Remember Serbs would take 800per turn and a tech Look at their strengh compared to mine
Anyway I can share as many as these as you want to see. Heres on for the road.
In conclusion, its clearly been demostrated that those myths made by civ4players who many years ago are simply BS.
False claims such as the player being able to organize an ungodly allience for the price of a bag of beans or something insignifigant as such, are clearly false. On any average difficulty or unofficially patched epic being played today you all see how the AI conducts itself at the trade table
This myth of being able to win with the "carrot strategy" has been exposed as another hollow attack on true strategy, probably was googled from Civ4 fanbois insult guide to civ3.
