I got really lucky in this game. I managed to form Prussia pretty early, almost immediately after the Reformation started. After the War of the Protestant League, I became Emperor of the Holy Roman Empire. Then, my first bout of luck happened: Austria's monarch died without an heir. My Prussia and my French allies fought against Great Britain in a succession war, which we won, giving me a Personal Union over Austria. I consolidated my hold over the HRE states through a combination of annexation and vassalization. Sweden conquered Norway and Denmark, forming Scandinavia, also strong allies of mine. As a result of the formation of Scandinavia, Russia lost much territory to them in wars, eventually becoming a rump state in Europe with vast, unusable lands. Eventually, they are converted to Islam by a Sunni revolt (I felt bad for them at this point, so I gave them some land out of pity.) I colonized much of North America as Prussia, and managed to keep a hold on my colony, and later colonies, as I colonized Australia and New Zealand, as well as the West Coast of North America. I had unified Germany at this point, and France turned on me. Helpfully, the League of Augsburg event fired, forming a massive league against France, consisting of my Germany, Great Britain, Scandinavia, Spain, and Tuscany(One of two major Italian powers in my game. The other was Milan.). We destroyed France in short order. After a few more wars over the next century, France was completely dismantled into three German vassals: France(a republic until the Revolution), Burgundy, and Toulouse. At this point, I got incredibly lucky again: Great Britain's monarch died without an heir. After a short war with Scandinavia, Germany and Great Britain were in personal union under me. Shortly after that, Scandinavia's monarch also died, and I became King of Germany, Great Britain, and Scandinavia. Toward the end of the game, I ended up in a war against Spain started by my colony in Colombia against theirs. I took the opportunity to release Aragon and Navarre. It was a great game. I'm sure I missed some things that happened, like the conquest of the Holy Land, but this is already a long post.

His Imperial Majesty, Hector of Anhalt, Emperor of Germany and Scandinavia; King of Great Britain, France, Prussia, Italy, Aragon, Jerusalem, Ireland, and Navarre; Archduke of Austria and the Netherlands.
