Arabia's ability seems amazing. That adds up to a large income bonus, and Arabia will probably control the entire world's economy once oil comes around, meaning more money/units/friends.. very versatile and powerful.
Rome, Russia, America, and Japan are all great. England is a bit specific but wonderful in some situations. India, Persia, Songhai, and France are pretty good. Iroquois is a bit underpowered sounding to me.... but:
I am incredibly disappointed by Germany and the Ottomans. Germany is supposed to be an incredible industrial civ, what the hell is this? A chance to get a bit of gold and a unit from each barbarian encampment. It would be different if you could make the encampments into cities or something but unless barbarians are going to be a huge part of the game (which would suck) then Germany is terrible. Plus the units barbs have are likely far behind... And Ottomans are even worse...




I want mah Germanz! Wah!
