Joseph, I do understand that one should be respectful of one's elders, and I mean that sincerely. Simply...too often I see you making claims that something is wrong or unbalanced in the game in GENERAL, when it will be as a result of the specific circumstances of your current game.
Case in point, the aforementioned AI to size ratio, and that bug where the AI wouldn't expand. With those two combined, I would expect nothing less than that screenshot.
Seven to twelve on huge, eh? Well, you can play your games like that if you want. I personally try to make sure the ratio is always constant with the base amount of AI given to a standard size map, on the grounds that that was what was recommended by the actual devs of Civ IV, and I'm sure they did EXTENSIVE play testing for standard.
So, I operate as if they know what's best.
Since huge is about twice as big as standard, I play with 14 AIs.
Just to give you my philosophy.
