Okay I decided to pick up Venice and it went somewhat ok at the start but it got real nasty when a Ottoman/GH alliance decided to take me on. I fought for around 5 years, and the AI kept trying to invade Corfu?(island off Greece) with it's 20k stack. So I blocked the straits, got some seiging happening and managed to grab Achea
. Naples, Siena were my other vassals and after a war with Ottomans I got them to release Serbia and Bosnia from vassalisation and got them vassaled in another war.
Hungary got big for a while but I took them down and scored Croatia as a vassal, and another war with OE got me Thrace and some more of Greece. Things were going pretty well, I was waiting for cores so I could form Italy but low and behold, France decides to come in and ruin everything
. They offered an alliance which I accepted, they then decided to attack Austria with it's 70k army vs my 25k army and they didn't really bother with the Austrian stacks
; and this happened twice. Then France decided to take Italian territory (Austria inherited 2 coutries) and annex Milan
So now I'm stuck with being unable to get back my cores because of monster France, so I think I might just go after India
Also I forgot to mention in teh OP that its IN3.2
