Greece Great Power in 1860.
In 1836, I spent 1 year switching through countries doing Event 60120. Eventually after destroying most of the nations that would be/are GPs or Secondary Powers in 1836 were destroyed, and then I got to work.
Scandinavia formed early on in the game and became the world's #1 Great Power, and I was left at about #13. There were 3 German Great Powers, so of course once Germany finally formed I was put up #9.
Portugal and Sardinia Piedmont were annoying, they were constantly colonizing the former Ottoman Empire and just the most random places in the world. There was a Crisis with Portugal vs Scandinavia on who got to Colonize Galicia, and you can guess who won.
Switzerland did very well (In my opinion at least), because I mean they actually expanded outside of their borders! In the game my goal was to form the Byzantine empire, so of course I had to beat up Portugal, but I had some problems with rebels and Albanian Nationalists (Lol). Then I started getting lots of Prestige, getting Sardinia Piedmont out of Constantinople, crushing the barbarians to the north, and then I was ready to form the Byzantine Empire! At that point I was #3, and when I clicked the event which forms the Byzantine Empire.... My game crashed.
North America was pretty boring throughout the game, I put Deseret in Michigan/Toronto because I knew it was just going to get destroyed by the stupid Californians, but then a war between Brazil and all the North American nations made North America interesting, which ended up with New England controlling all of the Brazil colonies in Canada (Which made them ranked 8th in the world and allowed them to colonize), Texas gaining the Brazilian colonies of Chihuahua, Louisiana, and Oklahoma, Cherokee gaining Missouri, and finally California gained the colonies of Oregon and Sonora. Brazil got crushed, but they're still pretty powerful.
The weird Cherokee and CSA borders are because I only gave CSA Richmond when I was adding North American nations, and Cherokee only had cores on those 2 provinces in Arkansas (Although I think the Cherokee turned out very nicely).
(Bad quality sorry)
In the later parts of the game (1850s), when Germany formed, Germany and Scandinavia had A LOT of problems. Scandinavia became one of the few nations that took it upon themselves to "Re-Take" the planet, and by that I mean colonize places that were destroyed. Scandinavia controlled the English channel, to the Spanish Galicia, and even parts in Russia, and that led to the war in which you can see above.
List of all GPs in the strange world. I will unfortunately be unable to continue this due to my computers constant crashing whenever I decide to play the save file, but whatever It was fun and it made the world look weird!
Sorry If I violated any forum rules or anything, I'm still kinda a noob to all of this (I just figured out how to take screenshots and where to find them).
