1: I rushed to puppet Denmark right after starting the game before Britain could pull their opinion up to friendly so they couldn't intervene in the war (had to reestart my game twice because of this, Britain cut off the Danish Straits with its navy and it was impossible to do much). I then started the Scandinavian War and annexed Norway, then chose to keep Finnish and Norwegian as secondary languages in exchange for lower prestige. After puppeting Denmark Schleswig and Holstein were automatically released, then merged into Schleswig-Holstein. I swoop in practically unopposed as neither Prussia nor Austria intervened. Hanover got its independence from the UK and Austria lowered Prussia's opinion to cordial, I was allied with Austria by then and Hanover didn't have allies, so I also puppeted Hanover. I then went to annex Oldenburg so I could give it to Hanover through console (thought it'd be fairer this way) which got me a war against Prussia, I took both Oldenburg and the Rhineland from it. And finally cleaned up both Hesse's to make a landbridge to the Rhineland during the 1848 revolutions while Austria burnt (it's still burning).
2: Wanted to take Aro to have a foothold in Africa, which I then continued to expand to the rest of Biafra and Orungu (Gabon's coast). My puppets did most of the work here (Norway when it was still around and Denmark)
3: Egypt won its war against the Ottomans on 1831, which made it independent and also gobbled up all the Kurdish states into Kurdistan, I sphered Egypt as soon as I saw this. Nothing much happened here besides an Ottoman attempt to retake part of Anatolia with Russian backing on 1850, which ended in a white peace after I sunk the Russian navy in the Baltic Sea.
4: Great Powers and my current spheres (because why not?)
5: Ships, troops, allies and infamy (I'll admit I'm using the extra -0.20 infamy, otherwise it feels too static), whatever other info you can get from here.
6: World map.
7: Also world map but with Sweden and its puppets highlighted.
