How Does Difficulty Affect the Campaign Game?

The AI seems to build more troops and attacks more.

Still thick as paste on the battlefield though

It also seems that the AI forms more large forces rather than small, scattered armies as it does on easy and normal. While harder in the short-term, this can actually prove to make things easier in the long run, as it means you don't have to spend as much time tracking down remnant, scattered enemy forces.

In general I find the AI to be extremely aggressive on V. hard.
