As Russia, I started out in the middle of a stone terrain, with very little natural resources. However, it turned out that there was a ton of Salt around there, which I claimed and made a boatload of money off of. Seriously, every nation wanted my salt, and were willing to pay a lot of gold for it.
Later, I decided to face off against China, who was like the fourth strongest nation on the map. We never liked each other, so I just thought it would be funny. However, I get the help of Germany, the Aztecs, and Poland against China, and we all tag team it. Poland and I brought my forces from the south, Germany came in from the west, and the Aztecs from the north. Most of my army consisted of Death Robots, so that was a lot of fun.
Eventually, the war ended with me capturing Shanghai and the Aztecs taking Beijing.
Moral of the story: Never face off against Mother Russia.
