My Brandenburg -> Prussia -> Germany game. I decided to do only "limited" expansion in Europe and instead focus late game on building my own colonial empire in Africa, India and Australia.
Some notes about the game. Only American nation to get independence was mini-USA. Golden Horde survived whole game and Russia never reached Siberia. Also, Ottomans did pretty well till the turn of 19th century when Russia decided to flood on Balkans and Ottos lost pretty much everything there either to Russians or rebels.
France went revolutionary and I pretty much stopped playing after the revoluationary war had ended. Just speeded up to the end and watched how Russia beated the crap out of Ottomans.
