Some of my observation by 1st time on World Map on Prince difficulaty.
1. Julious Cesar finally uses his advantage of starting possition. Now he has almost biggest Empire, containing Italy, Austria, Czech, Slovakia, Greece, Serbia y Monte(...), Yugoslavia, Croatia, Rumunia, Nacedonia, Ukraine.
In 600bc ! He has Cathrine, Hannibal, Mehmed II and 2 more vassals. Invaded Mali. A bit good, but inballancing.
2. Shaka finally is not conquering all of Africa by him self... Goood
3. Cyrus finally makes an Imperium ! Conquering Samraquand, All they way up in barbarian territory, and 60-70% of India real land (india was destroyed by him and Chineese). He has Ramses II as vassal.
4. Chineese nicelly expand (finally) and killed Choson in 3000bc... too fast.
5. America can finally withstand barbarians (or only this time) and lead a succesfull campaign against them.
6. Carthage can easilly kill off Rameses II.
7. Better AI defends cities less. Does not garrison more than 3-5 units, even if its capitol. Has problems building galleys, preffer Trireme. I saw Julious Cesar use stack containing 5 city raiders and 3 offence and 5 defence units as scouting army.
8. Looks like assassins are finally ballanced.
9. Judaism spreads slow. Only Mansa as its founder and 3 of my cities have Judaism. That 3 cities of mine are Rabat, Utica and Toledo, witch is build on lower island hill (im Spain).
10. Zoroastrianism spreads TOO fast. 3 times faster than Judaism when i was reporting it spread rate. In 850bc when Cristianity was founded (By Washington), Zoroastrianism was in 2 of 3 French cities, 2 British cities, 3 Ragnar cities, 3 of 4 bismark cities, All Julious Cesar cities, 2 cities of Rameses II, 3 of 4 of Hannibals cities, 2 of 5 Shaka cities, 5 Arabian Cities (including Tatar), 3 cities of Mehmet II, All cities of Cathrine (some were captured by Romans, Cathrine founded Zoroastrianism), 4 of 6 of Cyrus cities (before campaign vs Hinduistic India).
I have founded Islam, Buddism founded by Genghis has spread to Japan and China. Taoism founded in Gao, Mali, so didnt spread and was forgotten.
So i say that countries like Rome and Persia are a bit over powered. Now will play as Cyrus... Or Mansa Musa... or Mehmed II...
