Arabia's pretty nice, I'd want to live there.
Oda is standing, as someone noticed on 2K Forums, on what appears to be a default windows xp background.
Ramses looks pretty nice, detailed and what you'd expect from Egypt.
Germany's adds insult to what is already the worst civ. It's boring.
England's is a bit plain, other than that the only problem with it is Elizabeth. Her voice and hand gestures are just annoying.
America's is okay, not anything exciting, the gameplay's the same. It could be a bit brighter, too.
Russia's is pretty good.
China's looks like a cheap background.
Siam's has a pretty good one, although a third of it is covered by Rammy's hat.
India's looks nice, but not what I'd choose to represent the civ, even if it represents Gandhi.
Persia's is okay, but I thought it could use improvement.
Overall, I'd say all of them are better than they were in IV.
