- What are the scripted events for Milan, Genoa and Florence cities during the course of the game?
Major Urban rebellions against Centralised power. Expect Northern Italy to be tough to hold, they just want to be independent :p

Lombard League will manifest as one big major Northern Italian rebellion.

- Venice looks all but HRE. What will it start with?
Island of Venice and Istria. Venice is connected by a bridge of any kind, you've got to make a naval landing to even attack it. So if you are the Venetians, and you have a weak land army, but a very strong fleet, don't expect an invasion anytime soon, except perhaps Istria, but the HRE will be occupied with the mainland to even bother anyway.

Venice has the opportunity to create a maritime empire of enclaves from one end of the Mediterranean to the other...sound like fun?
