Thank you very much for the award, and I suppose it's my turn to pass the torch:
I write very image heavy gameplay/narrative AAR's, however when I read an AAR, that is not always what I'm looking for. Take the new winner, which has a narrative that doesn't rely much upon showing the game, yet whose updates captivate the story that CK2 can tell, if you let it. I nominate:
Norgesveldet – A history of the Norwegian kings by Nikolai
