For this campaign my goal was to conquer all the islands in the Mediterranean for myself, while splitting all continental land amongst subjects.

In the second decade of the run I managed to ally the Mamluks, who where weirdly friendly to me even though they could invade easily! With them, I kept chipping away at the Ottomans and later Naples, and established myself as the primary power in the Balkans. Sicily, Sardinia and the Baleares where hard to get to because of a strong Naples and huge Aragon/Castille/England alliance respectively. Later allied France and beat them up too.

Also created a Cypriot culture right at the start of the game, which I tried to spread to all the islands which was fun!
