My favourite moment when beta testing Heir to the Throne was my game as Napoli.
I strarted expanding northward and annexing few of the minors. The Pope get annoyingly attacking me or trying to meddle with MY minors, so fought many wars against it until reduced it to one province minor and force-vassalised. I continued my expansion more freely after that, since next big obstacle would have been Venice that had been my trusted ally. I was part of Venetian trade league as well, but had gotten strong and started to think of next moves. I couldn't build my own CoT as long as I was in same league, but I didn't have the money either yet although could gain about 100 a year. I had a very good plan going otherwise as well, since my heir had a strong claim to the throne and had stats that would have allowed few national decisions such as reducing Papal control. Going Protestant had become my long-term goal after the 3rd or so war against the Pope. I owned all provinces that would allow to become Italy when becoming cores in just a decade or so. I had a couple of vassals in Italy and my prestige was humongous with right ideas and cultural decisions, so annexation through inheritance was a matter of time.
Then things started to go wrong. I had put my national focus in my lates acquisitions in northern Italy to allow land reforms but that had given Venice a casus belli on me. Then Corsica rebelled from Aragon, so I quickly took them under my wing. Genoa decided to ignore my sphere of influence and made royal marriage with Corsicans, which after all were in same dynasty. This gave a casus belli on them, which I decided to exploit to snatch Milan Genoa had recently acquired. Genoa was part of Holy Roman Empire, but also earlier the Emperor hadn't really paid attention to my wars or had not given any decisive aid. Now Bavaria was Emperor and had grown huge. He actually did honour his obligation and joined the war, but I thought I could manage from my miscalculation. My ally Venice didn't honour my call to war though, but it didn't seem fatal. I proceeded to quickly occupy all of Genoa and fight off a few Bavarian armies. When I made peace with Genoa to take Milan Venice decided to declare war exploiting the casus belli and me being occupied, those no-good bastards.
My plan was to contain Venice while knocking off Bavaria out of the war. I had a few points warscore from battles already, so thought getting few provinces would make them sign a white peace. Unfortunately they annihilated completely half of my all forces in a great battle in Kärnten. After that I scrambled to make a defensive line around in Po valley and it looked I could start to recover. Then Aragon together with Castile joined the fun and landed armies on my rear in southern Italy. Following that Naxos joined the fun together with other minors and landed a few thousand infantry as well. Heck, even Tripoli attacked to sieze Malta.
I did my best, but was just completely underpowered. I spammed peace offers, but the AI wouldn't budge without getting provinces or forcing me to release states that I didn't want to give as it would have delayed forming Italy so much. First I bribed Tripoli to sign peace, which gave me Malta as a place that wasn't possible to reach by Bavarian troops with no navy. Then I got Venice to accept their neighbouring provinces and loosing few cores. Aragon accepted mostly money, while Naxos was content to humiliate me and get prestige that is actually rather hard to acquire as a minor. Unfortunately Bavaria occupied the released provinces quickly before I could raise any fresh troops. In the end their war exhaustion had grown very big domestically while rebels, mostly partisans or heretics, were even more constant in Italy. Following a Polish attack on them they accepted peace with me only releasing a few provinces that weren't necessary to form Italy.
That last epic war started in real life at around 7 o'clock on a Sunday evening. It made me skip Big Brother final even though I had watched it almost daily this fall. When I had managed to secure the last peace I realised it is 2 in the morning, which is always good when you need to get up at 6.30. I haven't been so deeply sucked into a game for quite a while.
