Further Feedback:
I have just reached Astronomy as Colonial Bulgaria.
AI Feedback-
Iberia- Upon further review, Spain has conquered the entire peninsula. What happened was Portugal spawned, then collpased by Cordoba. Cordoba was then, of course, obliterated by Spain. Portugal did try to respawn, but I don't think they even managed to retake one city from the Spanish, who conquered all the numerous independent cities.
Venice- As I mentioned before, their units were stuck near Ragusa. The stack has grown to around 25 units (min.), and they keep coming.
Germany- Conquered a collapsed Poland. Ridiculously powerful at this point. Lost its crusader kingdom due to Arab respawn.
Burgundy- Weak. Too weak to put up a serious fight against France, Genoa, or Germany. They collapsed early in my game. Then they respawned and became my vassal.
Genoa- Their only strength is position. If you go through Venice, Burgundy, or Rome, Genoa will fall really, really easily.
Hungary- Slightly UPd at this point. They respawned after I collapsed them by taking Buda. They managed to collpase Austria, and are once again in a strong posistion.
Muscovy- It's expanding really rapidly through former Kievan territory. Seems to have a really low score for some reason.
Lithuania- It actually is doing well due to a collapsed Poland.
Ottomans- Easy to defeat with knights. I did it during a plague for crying out loud. I then got them to convert to Orthodoxy for peace after obliterating their stacks.
Orthodox Diplomacy- The Ottomans, Lithuanians, and Muscovites all have a -1 hit for heathen religion with me, despite a commmon religion (Orthodoxy).
Bulgaria Feedback-
OPd late game if warmongerer- I managed to take Thrace and Constantinople early. Soon, I took Macedonia and Greece. I crushed Genoa by stroming through Florence. Now, I control all of that plus Tetuoan and Morroco. I have 2 vassals, Burgundy and Tunisia (Cordoba). I also managed to get 2 DPs with Turkey and Muscovy.
Science Advantage- It comes from the Round Church, I think. The Hagia Sophia also gives a lot of gold to keep the science rate high. I am well ahead of everyone else at this point.
Orthodoxy Advantage- I have around 80 faith points right now, and my stability is very high despite cities in Italy, Africa, Greece, and one in Russia. My overall stability is around +12.
I hope to post more info. once I finish the game.
