I've got a nomination:
I love narrative AARs, and Paradox games are the perfect environment for creating a detailed story, to such a point that in-game screenshots can be kept to an absolute minimum and still hold the reader's attention.
@naxhi24 has been writing a very engrossing Stellaris tale that has so far been a thrilling ride that I wholly recommend.
A Galaxy of Wonder is the kind of AAR you'll be sucked into, and you'll find yourself caught up to the current chapter before you realize it.
