Great mod, very impressive! I hope to see v3 in the future.
Quick question: is there a way to increase the difficulty? On very hard/very hard it's actually not hard at all to steamroll the byzantines and take everything in about 15 turns without even manually playing the battles.
As a side note, I accidentally figured out a way to play as "Bulgaria" on the stainless steel mod - start with Rus and do what the bulgarians did - run to the balkan peninsula (ukraine is un-defendable) and turtle there as long as possible. It's quite challenging actually
In any case, it would be awesome to do something similar with a proper bulgarian fraction.
Again, great work team Bulgaria-TW!
