Currently playing as the Soviet Union, which is going extremely well.
After turning communist my country was in quite a state, I had zero industry, low prestige and my military wasn't exactly up to standards. However I was clinging onto the 5th Great power spot, The USA and the Ottoman Empire were below (I can't remember the other one, Prussia maybe?) Anyway, I allied with the USA and a few other minor countries and set to work. Firstly, while Austria was at war with Denmark I went to war with them too and easily won Greenland and Iceland without too much trouble. I began influenecing as many countries as possible and tried to stop the German empire/North German Federation forming (I failed at that, they formed around 1842) It was about that time I decided I would conquer the world, or at least fill it with communits.
Annexed Khiva, Bukkhara, Afghanistan, Koland and a big chunk of Persia. In between all this I was expanding, building ships, improving my industry and I kept switching between the number one and two spot of Great Powers. Throughout this Britain was desprate to contain me, but ever time I managed to beat them back. It was all good, but there was a problem. You see, the problem was a simple one: China. It felt annoying, the way it just sat there, mocking me...the damn country wasn't even communist... China knew I was gunning for them and set up an alliance with Japan and placed troops along its borders.
Reguardless of it, in 1877 I declared war, and what a war. I lost very few battles and won alot more, the chinese couldn' seem to beat me you see, even the Japanese (who, might I add, are excellent fighters) It was excellent. At one point I saw an army of 7000 Soviet soldiers beat and army of 114,000 Chinese soldiers, That doesn't happen often! Suffice to say, I won the war and won four regions from China. It was all good.
By this time my sphere of influence had grown to add Zulu, but of course they didn't like that, So I annexed them then released them as a communist nation, which was very good fun (i'm currently about to do that to Korea) so yeah, thats pretty much whats happened so far, But I did just have a massive rebellion, and another, and probably another...
P.S. Egypt was screwed from the very start, the poor guys have a revolution putting a dictator in charge, then the unlucky folks were invaded by the Ottoman empire, portragual, two Scillies, Belgium, France...the list goes on. Only a tiny bit of Egypt remains, I think of that as 'Free Egypt'.
