Stories are often how we share our bets moments with others.  I would love to see a generative AI type tool take all the in game descisions and events and weave them into a story at the end.

Use the build up of war support to fabricate a story for the start of a war, use pivotal battles to create a war story along with it, etc.

Every game would easily have enough datapoints to feed an AI and get a respectable story.
