Having a pretty good run with the Pala Empire, off in the far eastern corner of India. Used a Charlemagne start and over a couple of generations got my centralization and crown authority high enough to get Ultimogeniture passed in all three of my kingdoms (Bengal, Bihar and Kamarupa which I forced into submission early) so that my fledgling empire didn't get broken apart. Steadily kept adding territory (and got lucky when my restless cousin raised a host and conquered Lanka, then died childless and I inherited the kingdom) and eventually declared the Bengal Empire in 887. Current save is 898.
Now to sweep south and absorb the Deccan kingdoms, then west and north to absorb Rajastan. Then I can raise a true Imperial India before the Mughals arrive and I kick them to the curb.
I only hope that the Abbasid Caliphate fractures before then because holy Giant Green Blob of Allah.
In Europe proper, things have gotten a bit derpy. Charlemagne the Cruel never bothered with Lombardy, so there is still no Holy Roman Empire, only Germania, which is about 5 years away from de jure incorporating Middle Francia (Lotharingia/Lorraine), 25 years from incorporating West Francia (France), and 33 years from incorporating Aquitaine. Oh, and 27 years from incorporating Frisia.
The Lombards have steadily crept southward through Italy, save for a few Byzantine provinces in Napoli and Sicily, and the Holy See. If the Lombards eventually take Sicily from Constantinople, they'll no doubt resurrect the Empire of Italia.
In the East, Poland is a sprawling mess of a kingdom, stretching from Lausitz to Murom, but with lots of pockets and enclaves outside its control. And it's still Slavic pagan.
Rus is concentrated around Novgorod, and its king is a Mordvin who follows the Finnish gods.
The Ummayyads completely dominated the Iberian peninsula and declared the Empire of Hispania. The only Reconquista has been a tiny German salient holding Tarragona.
England is a godawful fratricidal mess, with the only regional hegemon in the British Isles being Pictland.
Likewise, central Asia is a fragmented morass despite the Tengri reformation (or perhaps *because* of it)
Shia Islam is extinct, and Romuva paganism is nearly extinct.
All in all, this could be an interesting one to watch. A Europe with potentially no independent France, a Muslim Spain, a Scottish-dominated Britain, an Italy separated from German dynastic struggles, and no HRE?
