Haha yeah, I should save more often. To be honest, I think Korea was pretty far behind, only 'cuz I isolated it from the rest of the world since the only other civ around was Japan, which actually did expand throughout the island, but I had already taken over most of the eastern half of China.
I think it's the maze of jungles that makes it hard to expand, at least within India - to explore the world, I had to carefully navigate certain sections up and down to get through.
The Near East civ's were doing pretty well, Persia and Babylon were pretty advanced. European civs were trying to expand, except that for them with so many civs it's hard to expand too much - Only Russia really had the luxury of massive unobstructed expansion.
Game's pretty fun though, I enjoy it a lot. Great job!
