Playing as Venice, reached 1242, to be continued. Doing pretty well, having built Venezia, Parma, and Firenze in mainland Italy, Fiume, Spalato, Durazzo and Corfu in Adriatic Coast, and Bastia in Corsica about some years ago (Genoans hadn't settled there yet?). It was Monarch, believe me

.
Some observations:
1) Vassals: Currently having two of them, Genoa and the Papal States

. Didn't know the Papal State could be a vassal....
2) Papal State, vol.2: When built Durazzo and Corfu, a message appeared, asking me to pass control to the Pope. Kinda strange... (it was like the ''x city wants to return to its rightfully owner''. Logical for most civs, but for pope...)
3) Tech rate (revamped): Yes there is a change, it slowed down as it needed.
4) Other states state: Franks are the only collapsed, after finding themselves losing a war vs a Burgundian-Spanish alliance. Cordobans are the first, followed by Arabs, Byzantines, me, and Kyiv (I will tell you when Keshiks come...

). Burgundian is unstable as well as Byzantines (btw first time I see Burgundians build Besancon).
