How much the AI cheats this time?

[Kamamura]

In Civ4, it cheated a lot. By looking into the configuration, you could see it was able to purchase units with a fraction of cost, building ridiculous stacks everywhere, only to aimlessly shuffle them around. It also cheated with exploration (omniscience), so
"trading maps" was more or less for nothing.

So how it is this time? It it capable of coordinated attack, overseas invasion, does it build forts on chokepoints, does it negotiate meaningfully?

Or is it the old mumbo-dumbo, decorated with lots of colorful bells and whistles?

it seems like the AI cheats a lot less on a few notches above the non-cheating one compared to previous civ games

Ok, first, the AI in civ IV is not omniscient It has some bonus in visibility, true, but that is to compensate the lack of memory about what units were there in the previous turns, but it has no omniscience. In fact civ IV AI was the first in civ games that has no full map knowledge.

And well, Civ V AI ... I'll let you with the relevant XML on Prince ( the "balanced" level, equivalent to the civ IV Noble )

One thing is true, the AI does not make ridiculous stacks any longer
