Spain has most of South America and Mexico.
Malindi dominated east Africa and stretches from my border near Mutapa all the way to Ottoman Egypt, where they're shared colors makes things a bit confusing.
Tunis has most of North Africa and pushed south to eat a good chunk of the Sahel.
Kikondja conquered most of the Kongo outside of what I took in the northern and southern borders.
There are no other nations of note.

I did lose one war in the early game, to Burgundy (allied to Muscovy). They were annoying for about 80 years before being subdued, but didn't die fully until much later because of other priorities.

The most impressive AI nations however were Bengal, Malwa, and Iraq, who end up being great powers 5, 7, and 8 respectively. Bengal stretches from Golkonda almost to China's east coast, north through Tibet and south through to the border of the Indochina peninsula. Malwa has 2/3 of India, outside of my lands in the south and Bengal's encroachments in the east. They used to be even bigger. Iraq has most of Persia, Afghanistan, and Pakistan, and stretches north to Samarkand while also having most of the southwestern Arabian peninsula. All three of them did this largely without my intervention. I never once fought them (though I sniped Malwa's wars a couple of times).
Russia's border are mostly historical, though they didn't get all the way east (eastern Siberia remains uncolonized because I didn't want it).
Malacca has most of Indochina and the Malayan peninsula except for their original southern holdings, which I have.

As for state the world:
The Empire went Protestant, mostly because of my intervention as league leader. Aside from my own land, most of the rest of Germany and Scandinavia are Protestant because of Brandenburg and the Nordic nations. Lituania is also Protestant for some reason (they switched back and forth multiple times).
As you can see Brandenburg did extremely well, which makes sense because they were my ally until near the end of the game. They're the 4th great power.

Offscreen there are VAST colonial holdings, matched only by my Ottoman game in scope. I have most of south Africa and much of west Africa, the Gulf of Aden region in southern Arabia and eastern Nubia, most of southern India, all of Australia, New Zealand, and the Philippines, most of Indonesia and Malaysia, a good chunk of southern China, 2/3 of North America (the Spanish and Portuguese have most of Mexico and southern Louisiana), and the entire Caribbean (FINALLY getting the achievement after several failed attempts in other runs). So no much contiguous land, but tons of great trade to fund my empire while the continental breadbasket gave me lost of development. By the end of the game I had close to 30 merchants, some of which I was struggling to find uses for.

The crowning achievement was The Grand Armada, which was achieved in 1807 or so. I actually went even farther because by then I was drowning in money. I just attached 50 ship armadas to trade fleets after awhile since 200+ plus for navies was already excessive.

Played in 1.19. The goal was to get several England and colonial related achievements, most of which I was successful in doing. I was aggressive against France early on, choosing to eat them in chunks instead of PUing them. I went after Italy and Iberia mostly for that trade money (and to get All Your Trade Are Belong to Us). I toyed with the idea of becoming the Emperor for awhile, vassalizing some electors, and was elected Emperor for a couple of generations in the 1700s (though I lost it eventually, making me decide to (unsuccessfully) try to destroy the empire. That's what the current war was for. I should have started it a couple of years earlier for siege times. If I'd done that I would have been successful for sure. England itself is rich due to boosting development for An Industrial Evolution.
