Poll: scale the difficulty of each campaign

[Moros]

Can't tell which is the hardest. I've made a succesfull campaigns with Hayasdan (where I remade the persian empire), conquered egypt and India with Saba and conquered Italy with the Sauromatae. The hardest campaign I had was an Arverni game actually, my first 1.x campaign. But that was because of roleplaying rather than the campaign.

Saka & Pahlava I tweaked and modded lots of things but for them there is no second option than offence is best defence.
If you have not much experience on cavalry warfare with horse archers which needs time consuming micromanaged battles, do not try them
I hate blitzing but my eternal enemy AS does not give up sending full stacks against me until I destroy her.
For me it is very easy to play with them because "I know myself and my enemy very well" and "I never attack strong points of my enemy while their weaknesses is waiting for me."
