I have only one AAR, which I've just completed. The title is
Dominus Regni Poloniae and it originated from the idea of trying to replicate the achievement of
Wladyslaw the Elbow-High, who, after a turbulent youth and even more difficult middle age, managed to seal the reunification of the Kingdom of Poland when after two centuries of partitions the crown was eventually worn by a usurping, invading foreign ruler. In CK2, not only was Wladyslaw represented as a vassal of the foreigner, along with everybody else in Poland, but he lacked a claim on the kingdom title, and all of the other dukes liked the usurper, which was harsher than in real history. It took me 11 more years but I managed not to lose land in the process. I do cover the personal price Wladyslaw paid for it.
The AAR changes in many aspects after the unification and liberation completed and it was clear the restored kingdom would survive. I kept playing and the game took a different turn. In fact a much different one. From a history tale and a largely mournful, solemn lesson (much more mournful when it comes to Wladyslaw himself, compared to real life, as you will see (or not)), it progresses to a semi-gutsy mostly picture-told tale with an occasional dialogue or a piece narrative when I felt like casting some light on a character I felt particularly strong about. That wasn't always the ruler himself. In fact, the women generally tended to be better, more capable and more interesting than the men. Nobody got more attention than a certain Berta Orsini, although Leontia Palaiologina 'the Wise' was quite a character too. I do some unorthodox things (if you want to see Poland in Abyssinia, this is the AAR to go), which, in a certain sense, is connected to a tale about social order, which finds an opportunity to be questioned near the end of the AAR when three subsequent kings make a certain very controversial move. But one that wasn't totally unconnected with the rationale underlying certain previous difficult decisions.
I try to answer the whos and whys and give the player ample notice about what's going on, so if you enjoy a potentially lengthy, homely AAR where you're told about almost everything, almost as if you were being shown the game, this is one like that. I also try to explain things I'm doing on the technical side in out-of-character notes. I tend to refer to events from previous instalments to help you bridge the connection so that you don't have to rack your brain but without making painfully sure that you don't miss utterly anything (I bring back the most important things, as well as the potentially finer minutiae that might be easier to miss, and it's mostly the mid ranks which are left to the flow).
I can't promise you the fine narrative or the spectacular effects of some of the most popular AARs but I hope you can enjoy the tale without calling it a wasted time. Feel free to drop me a line about just about anything.
Oh, and there's not a single assassination in the game. And only one 'fabricated claim' (that should be in the game anyway and is explained in gameplay terms).
EDIT: And two more:
The Lives of the Saints: An atypical AAR covering only the reigning time of each character and not his dynasty. It goes through characters of mediaeval saints present in the game (there is a good number, enough to keep going for a long time), starting with Louis IX of France. It has only just started, so we're at the beginning of Louis's reign. I'll spare you the (b)elaboration of the goals and intentions of that AAR. Just go and see if you like it. I'll give you one spoiler, though: it's not a narrative one, it's gameplay. Oh, maybe another one: it can have the side-effect of giving you an idea of who, when and where to play, gently introducing the relevant background. But this is not the primary goal.
Land's End: Starting as 'Earl' Kadoc of Cornwall in the William the Conqueror historical start. He has Breton culture, not Welsh, and rules from the castle of Tintagel. This is a "lite" project, mostly to give me something else to burn energy on when waiting out the necessary time-outs between updates of the LoS, which is a more ambitious AAR. I do what I feel like, both in the game and in the AAR, although it's gameplay in general. Under the first ruler, it starts from humour and is about to take a tragic turn. I don't know if it will be cheerful again but it's possible given the third (expected) ruler's personality.
