The Brazilian Slaughter
Arcane
Once or twice I've seen Hindus conquer parts of Persia, but very little comes out of India because it's bottlenecked tightly at Afghanistan. You need a very strong Punjab to break out, and Persia usually has very strong Abbasids or Seljuks or Mongols. Hopefully Tibet will help because it connects India to other parts of the world instead of just putting it in its own little corner.
I've seen a big-ass indian power starts eating parts of Persia in my last Zoro game, but that was after I had killed all the local muslim powers in Persia, Afghanistan had been turned into a hindu vs muslims vs buddhists vs me clusterfuck and the Abbasid blob had broken up in pieces.
The reworking of the Middle East and Persia should also help by decentralizing powers. Persia used to be humongous and now it's significantly less so, making its peripheries easier to conquer.
Did they take out provinces or did they just diminish that HUGE Kingdom of Persia into something smaller?
I also frequently see the lower Arabian peninsula fluctuate between Ethiopia and Muslims. The introduction of the Kingdom of Yemen should help whoever has it to hold on longer.
I have never seen Ethiopians in Arabia. Abbasids and other muslims always run million man trains on it. Perhaps that has changed in the lastest patch, but Ethiopia keeps getting rekt in my games.
