I finished this scenario today, on victory points. I played the sassanids, better known as the Persians. It's not a barbaric tribe, so I built both wonders. The heavy cavalry is far inferior to the barbaric units though. It looks as if the warlords are extremely powerful. I had to cleanse the world of the barbaric tribes who wanted in through my back door near Stalingrad.
I'm currently playing the medieval scenario. Fun so far. Poland is having a hard time
