Most Difficult to Conquer

In Germany you can have the most powerful army you can afford: you won't see them under those damned trees...

At least in germany, you just need some solid spearmen in the frone, and pump out tons of archers and slingers, and never try to attack first... thy'll killed in drovs

Archers? Slingers? In deep forest?!? O.o

Right, use some chariots as well. Oh, and artillery works excellently in forests too.

Maion

What the....?!? O.o

I think what he means is that missiles work well against unarmoured opponents. I agree that they are less so in the deep German forests...

The steppes are a lot harder when the Samartians refuse to make peace. Urgh

You do realize you can negate these forests partly? I mean: stick to the roads, stay out the thick of the forests, build forts at the end of your turn,... and try not to fight in the winter (less hitpoints for your generals, higher morale for the opponent,...). It's still costly, but doable if you really want these smelly swamps to be civilized.

The easiest to conquer would be Makedon. The AI simply can't handle phalangites. One single charge in their back and argyraspidai or hysteroi pehzetaroi are dead or broken. (Just don't fight them on the town square, and outnumber them).

I never much bothered with the steppes if I'm not a nomad faction myself. HA armies are too hard to defeat and the settlements there are practically worthless. As for Arabia,their troops are so lightly armoured that you can just shoot them to pieces with archers. Also, the main Saba cities are clustered together so you can take them within a few turns, while their cities along the Persian Gulf are easily taken from Persia by a naval invasion. By the time you are bothered by them,you invariably control either Egypt or Babylonia.
