That's a good way to distinguish your bog-standard AAR from an AH Series Replay.
A Replay was a detailed record of each DR/dr, effect, and move. But it was more than mere chronicle with a dash of Herodotus colour and commentary. Like better AAR, it was prefaced with pre-game analysis. The longer format also encouraged extensive mid- and post-game analysis. What's more, the Replay benefited from the insight of a third-party with no skin in the game. How many times have you had to bite your tongue as you watched players misplay an effect or fail to see an "obvious" course of action? IMO, this is one of the strengths of a Replay.
I view AAR as something akin to scenario analysis with the benefit of hindsight. A true AAR tends to be more more businesslike, something that Thucycides might appreciate. Unlike a scenario analysis, which focuses on the card and the playing area, AARs provide "proof of concept" for such analysis. An AAR therefore tends to focus on the test results--what worked, what didn't. As a result, I often find them more useful than the kind of scenario analysis found in Schwerpunkt, for instance.
I'd like to see a hybrid Replay, one that records data for verification, but which doesn't waste limited page real estate on every DR, etc.
Why do you think that there is "diminishing" room for a grognard's voice? The more the merrier!
I'd happily subscribe to a magazine dedicated to hybrid Replays if they were written by the likes of Mike McGrath, et. al. But I think it'd be a tall order just to get a single Replay published in each ASL Journal.
