Seeing as I have yet to win a game 
.... I hope someone will post a video of the ending credits showing off the improvements, so I can properly appreciate Keith's labors.
It's nothing impressive right now, just a box with a bunch of text, but it's a step in the right direction.
Procedurally-aggregated narrative sounds quite nice.... especially if we could somehow identify significant battles / close calls / valiant defenses / last ditch suicide attempts to save the universe as we know it , determine a name for them --- "Battle of the long knives" style, and have some sort of text for them, along with stats for that particular fight (along with stats for the entire game).
Recognizing the battles would be nice, and is doable (albeit complex), but would be pretty tricky to get enough sanity checks so that it doesn't do silly things. Even with a lot of work, y'all would basically have to deal with it not realizing that the battle was over despite the 100 cloaked raptors you tucked away in some outer corner, etc.
More focused on lower-hanging fruit like whether there's a dyson sphere, whether you freed it, whether you then enslaved it for yourself, what happened to each rebel human colony and captive human settlement, how many planets you captured, how many planets you nuked, etc.
