What difficulty are you playing on?

[Simmons]

For me settings are:

Campaign map: very hard, AI need all help in financial way to be able to provide troops.

Battles: medium, mostly because AI gets more money for troops, that way I might win more but AI have more money for troops

Scale: Large or medium, AI drain cities too fast if played in huge.

If I play on huge its VH/VH

I was under the impression that EB "topped up" the Ai factions populations but I can't remember where this impression comes from.
