Will do.
1492:
Asia Minor: The Ottomans force-annexed Dulkadir in 1455, and Cyprus from their Tunisian allies in 1461; soon after, they DoW'd Athens, annexing the Knights and taking Albania (from Ragusa) and Morea by 1474. They caught Serbia without allies in 1477, and annexed Tuscany and Sochi during a war with Georgia in 1490. Tuscany's and Georgia's third ally, the Papal States, would probably have been next - the Turk still had 40,000 troops in Firenze - had their government not fallen.
Ak Koyunlu has been taking in war what Qara Koyunlu gained by defection from the Timurids; unfortunately, they haven't been quite quick enough to take out QAR entirely.
France: Brittany, without allies, DoW'd Bourbonnais in the mid-1450s, and very quickly found itself losing all seven of its noncapital provinces to France, which turned around and diploannexed Bourbonnais itself immediately after. Burgundy found itself in a series of badboy wars in the 1460s, eventually losing its Irish possessions to defection and Holland and Zeeland to Friesland. In 1464, it annexed Brittany; Charles the Rash stayed there until he died fighting rebels in 1470. When the bug with the inheritance became clear, I switched out to the old version; in 1476, Austria inherited Burgundy in name only, receiving only Flandern, Brabant, and Luxemburg - Brittany and Munster were freed, and the rest went to France. Unsatisfied with the five provinces it received, France quickly annexed Brittany and took back the three provinces Burgundy had previously lost in Ireland.
HRE/Scandinavia: Denmark has waxed and waned, having gained and lost Oldenburg, Hannover, and Mecklenburg; on the plus side, they managed to take back Jamtland, Gander, and Greenland from the Swedes (all of which they lost in 1459), and have owned Istria since 1455. Silesia and Moravia are Magdeburg's, who also held Oldenburg and Hessen at one point. As with Brandenburg, all of Saxony's current non-core possessions were picked up through rebel defections. Austria has been picking up vassals left and right; Mantua, Salzburg, Baden, and Magdeburg (and
their vassal, Saxony) pay the Habsburgs tribute. The only land they picked up besides the Burgundy inheritance was Zeeland, after it declared independence from Friesland.
PL/Russia: Muscowy took Suzdal in 1453, Tver in 1460, and Karelia, Kexholm, and Ingermanland in 1463; gave up Tver, Ryazan, and Pskov to the Polish-Lithuanian juggernaut (which has otherwise remained quiet) in 1468; and took the Siberian tradeposts in 1470. Lithuania, which despite remaining Poland's vassal is starting to look scary, was further boosted in 1488 by the defections of Memel (from Sweden) and Vorones (from the Horde).
Sicily's been rather amusing: the entire island broke off from Aragon, which took the western half back; Naples then force-annexed the remains in Messina, only to lose it and Apulia in a war with the Pope, who promptly lost both provinces in a government fall during their war with the Ottomans to - surprise! - an independent Sicily again.
Iberia - but this is better shown on the world map.
The Portuguese Ai doesn't know what every,
every human Portugal does - ally with Spain. Spain is your friend. Keep Spain happy. Thus, Castile sacked Tago in 1484 and started dropping trade posts in Africa, and when Portugal's government fell in 1486, it picked up Kribi (which is a city by now), Gibraltar, the Azores, Oporto, and Algarve, and trading posts in Fernando Po, Recife, Bourbon, and Mauritius. (Douala was burnt and resettled).
All that green in Persia is the Mamelukes, who picked up Hormouz and Birjand from a Timurid government collapse, and the other three from Baluchistan in the first days of 1492.
East Africa: Ethiopia and Oman independently declared war on China around 1478, and burned all four of their trading posts in East Africa. Oman's been making an impressive comeback from their miserable start in general.
China has been at war continously since 1478; they've lost two provinces through defection to the Chagatai Khanate and two more to Manchu; a one-province Korea declared independence in 1488 and got their white peace exactly three years later.
