After Action Report
An AAR or After Action Report is a write-up of the events in the game from a fictional "As if it were real" setting. It can either be done as an after the fact historical narrative as might be found in a history book, or it might be a third person story, more like a novel.
AARs are generally written from the point of view of the nation that the player used when writing the AAR, although this is not always the case.
