Just imported my Indo-Persian game into EU4 (which I haven't played in a heap of months). Spending the first 20 years or so just getting a grip on the new mechanics and tidying up the borders (and converting some cultures).
Importer did some weirdness with giving Mongolia a sliver of provinces almost to the Indian ocean, but this problem resolved itself in short order thanks to masses of Indian separatists and an AI that actually does try to sell provinces now. I was gracious enough to buy the two times it offered, since I have more money than Shiva anyways.
Took Gahrwal in a quick war so I could form Bharat (despite having been the unified empire of India for hundreds of years). Also took Bhutan and Manipur, and have a slew of protectorates around my fringe. Reclaimed all the Persian holdings that I had lost to the Arabs towards the end of CK2. Now I'm wondering if I should focus on internal development or go for a massive land grab and expand west until I hold the Holy Land (now that I don't need to worry about endless Crusades if I do).
Or expand west until I find China and then try for a massive Indo-Persian-Chinese empire. One interesting bit is that I imported with Western tech, so all these south Asian minors are rapidly Westernizing. If I push west, I have to roflstomp China quickly, or I risk letting them westernize hundreds of years ahead of schedule, which would have huge ramifications for the rest of the world. At this point, I have a huge advantage in conquering/colonizing in Asia, because the Western powers are relatively small and won't be able to reach Asia for a long time.
Primary European powers:
Knights Templar (which appears to be filling in for Spain -- they won a Crusade for Iberia sometime back in CK2 and have kept trying to retake the rest of the peninsula)
Lloegyr (Breton England)
Norway
Sweden
Germany
HRE (considerably weaker than normal, only 24 members, mostly in Italy and eastern France)
Carpathia
Poland
Byzantine Empire (all of the Balkans, southern Italy and western Anatolia)
The Arab Empire is still around, but heavily truncated to mainly just the coast of North Africa, bits of Andalusia, the Levantine, and western Anatolia. Mecca and Medina were converted to Hinduism a hundred years ago. One major beneficiary of that is Abyssinia, which survived as an intact and stable Monophysite kingdom, at one point reaching all the way into central Egypt.
Should be an interesting game. There's no danger of "losing" the game, but I'm curious to see how things develop organically.
