Differences between difficulties

[Dead Guy]

I found the camera is restricted in Very Hard but not in Hard.

Previously I believe the camera was only restricted in battles where you were the attacker. As the defender you could always look at the entire map. Now you can always freely look at the entire map in Hard, but never (?) in Very Hard.

At what point in the difficulty levels (if any) does the AI start to cheat?

[hamysho]

The computer players get bonuses to production on the campaign map and to unit strength on the battle map. On normal the computer gets a handicap to production. So there is no perfectly even setting in Shogun 2.
