On the topic of the hardest, is there any possibility to survive as Sardinia? Every time I tried them I saw Aragon invading and annexing. If it's not Aragon, it's Savoy. Haven't tried a statistic on 20-30 startups to see how many times it happens, I just gave up the 7th try or so. While trying other countries specially to observe Sardinia, it happened in a number of cases to survive the same wars. What should I hope for? Vasalization by Sicily? I am open even to gamey suggestions, just to not involve editing/cheating.
