Some advices from my Byzies campaign:
- Ally with Hungary and Kievan Rus in the very first turns. Alliance with Hungary will secure whole Balkans cause they are not keen to break alliance. In my campaign they've did it after 250 turns. Alliance with Kievan Rus will secure Kaffa province, which otherwise will be rushed by them and you don't have funds to keep armies there or transport them from Constaninople regions
- In first 20 turns recruit every poor militia that appear in the pool and rush rebeled Scopia and Sofia otherwise Hungary will do that and in this game best ally is weak ally
- don't wait for venetians starting a war, hit them first and conquer ragusa. After losing their only castle they are as well as finished and you can even make them your vassal (in my campaign they agree without any conditions) If they take rebeled Zagreb or Belgrade try to retake it and give Zagreb to Hungary (region bordering with HRE is not what you want)
- Sicilians gonna land on the west coast of Pelopones so keep strong fleet there and intercept any ships. You can build fire ships from the beggining of the game.
After these steps western front is secured and you can start to push inti Minor Asia:
- Turkey has very weak early roster so you not gonna have any problems with beating them. Only their massive HA spam is preety annoying so build as much Mourtatoi as you can (Build advanced shooting range in Corinth and put some high chivalry general to Andrianopole to upgrade it to castle). After conquering some turkish provinces you would have a possibility to recruit decent Turkish Archers.
- Fatimits are much tougher with their Arab Cavalry and masses of spear infantry but they're no match for Scoutatois (recruit as many as you can, probably the best early unit in this whole mod)
And beware of Jihads and some scripted suprises like venetian stacks appearing from complete nowhere near Constantinople
