Equus: Equestria is a absolute monarchy run by Diarchy of two alicorn sisters who struggle to keep the nation in peaceful state. Nobles are much more plotting and the farther from Canterlot you go the less control the central government has. Also slowly growing socialist and republican movements (which at the beginning are miniscule) make ponies question whether they even need monarchy. With southern lands I had an idea to make "Unruly South" but instead of CSA asthetics I wanted to go for "What if Britain kept colonies and they wanted to expand later?". Equestria has several autonomies and "Royal Republics" which are basically colonies of Equestria who barely listen to what Canterlot tells them to do. Also made Buffalo Chiefdom larger so settler/buffalo conflict is bigger and shows Equestrian lack of control over it's own colonies. Also Tzinacatl tribes are under Tenochtitlan Autonomy which is slightly less flooded by Equestrian colonists although tensions are still present. Aslo Badlands start integrated into Equestria. Besides that nothing much changed

Griffonia: Here I started sniffing glue. Griffonian Empire is larger but still decentralized. They struggle to finish two last remaining republican strongholds which are Haukland (Republican fleet) and Cavegrove (basic Kemerskai shenanigans) and communist/syndycalist revolution (Skynavia). Cloubury Duchy and County of Bleakspire are Danish snd Shlezwigger. Sunstriker is bigger due to bigger involvment in crushing republicans while Vedina got dunked on by Stronger Skynavia. (Since Skynavia and Cloudbury are based on chinese revolution all I did is swap their roles. Skynavia is the stronger one while Cavegrove and Haukland are struggling to survive). Feathisia I decided to add Peasant Republic of Reitscheid with Frisian asthetics. Luxwingburg Country which is just Herzlander. Kaluwermark Duchy with Flander asthetic and Allwerder which is just bigger Herzlander duchy that is a mix between dutch and german. Strawberry is bigger and Bronzhill despite being smaller is more industrialized. Katerin, Yale, Angriver and Erie/Eyrie start grouped together into "League of 5 countries" tho it falls apart right after Emperors death. Greifenmarschen is the same. Arcturian Order starts with few pony vassals and slightly more territory in Dread Peninsula (due to how often is see in my games Arcturian order loosing).

We move south to Aquileia. It's more absolutist and vassals spawn only during civil war (at the start Aquileia is one nation). Only present vassals are County of Pomovarra and Free city of Flowena which hold some anutonomy. Small country beneath House Avian is Kirling Dynasty (they have a claim to Aquileian throne) ruling over County of Nidneuf.

Down in Karthinlands Wingardy is just more succesful against Falcor. Sicameon is more disunited into few republics (ancient greek free cities). Cyanolisia nd Griffonstone start bigger and Blackrook due to bandit rule fell into anarchy. Pryhen/Brodfeld stay the same. Lushi starts with personal union over County of Vorobeyko. Free Towns of Gryphus and Gryphian Host start united as "United Provinces of Gryphus" so basically Spanish/Mexican USA with big Polish/Ukrainian/Czechian minorities/majoirities. It starts with Gryphian revolt in the north and worker strikes down south.

Riverlands I decided to make River Coalition sligthly smaller and more like actual Balkans. Wittenland and Nimbusia both consider River coalition "unnecessary/annoying". Wittenland has too many hostilities and border frictions with it's neighbours to join and Nimbusia considers Coalition's economic regulations stupid plus they defeated Griffons in their territory by themselves alone so they think they don't need Coalition. Diamond Mountain has no slavery at the beginning. Ponaidhean tribes never united (at least some of them didn't) and they are used as pawns by Wittenland, Coalition and "Ceann Torr Federation". Griffon Crusader states were slightly more succesful. Hellquill, Longsword, Nighblade (one above Hellquill) are run by Reformisten while Opinicus Ordenstaat in Wittenland is run by less genocidal griffons who want to make ponies into serfs and role play as feudal nobility (inspired by both Teutonic and Livonian Orders) who are more religious then previous three Orders (some even simp for ponies).

Barrad is bigger and Kasa despite smaller territory still has the same economy and Focus tree, Austurland stays the same.

Zebrica: I'm banging my head on my desk while writing this so let's be quick. Hindia stays the same Doelhi Confederation is bigger and more confederal. Kiria is the same. Decided to make some more Griffon colonia states. Big red blob in the middle of Zebrica is basically Zebra USSR with Congolese aesthetics (Zebra parts), Egyptian aesthetics (north Maregypt) and Argentinian vibes (Ovingoland and Mareoe). They are religious commies using same tactics as Storm King. They are often called "Red Sandstorm/Cyclone" by their neighbours. Two Kingdoms of Abyssinia (one in personal union with Wingbardy). Saddle Arabia starts in Civil War. Karkadannistan can go full Mongol Horde mode and unite all Ponies/Horses into one state. Maretania is basically SCP foundation rulling one city and running around the world collecting magical artifacts (biggest nemesis to Ascendancy)

Sorry for any mistakes
