I love the map. It is actually amazing how balanced the civs were throughout the game.
Although, I used the "raging barbarian" option in a hope that it would curtail the expansion of the eastern civs. The problem is that it worked too well in some ways. It took a long time for Russia to gain parity with the rest of the continent, although they eventually moved into second place. In hindsight I would probably leave this option off, because I like the prospect of fighting a powerful Russia that can throw masses of troops westward - just not so powerful so as to be impossible to beat.
Another thing I did was slighly alter the positions of two coal resources within German territory. The reason was simply that they were both in what I felt was an optimal place to plop a city, and I just hate losing a resources production bonus because a city is on top of it. Perhaps that is a wussy way to play, but oh well.
It isn't like I added resources or anything, just gave them a one-tile move.
As for the Greeks, you may be right, but they actually seemed to do surprisingly well in my game, being in the middle-ranks for the whole game. It might be because the sea helps to block out barbarian invasions, allowing them to focus their military northward to further their growth.
The civs that seem to lag the most are the Celts and the Carthaginians, although the Celts might be stunted because they are next to Germany and I purposely try and crowd them out.
When I play again, I will probably turn raging barbarians off, so as to make the Russians more powerful.
