* Added all the patrician houses for Venice, Genoa and Pisa
* Added some flavour for better immersion
* Added counties for Gaeta and Amalfi and added those in as playable republics in the first start date
* Improvements to succession mechanics to ensure playability especially of smaller republics that can't have patrician houses yet and to avoid small towns stealing all your heirs.
* Added the later Dukes (in-game counts) of Gaeta as well if you really wanted to play as the House of Ridel for some reason.

Paradox had added the patricians of these houses in some very strange places so there was a lot of fixing of history files.
