Is it in the realm of possibility for a log of events to be generated?
I've seen some requests for viewable turn replays, but what I have in mind is a text summary of battles fought, moves made, arrivals and events. The game does this for each turn, and it would be great if this could be saved as a file. If this file could include the details of each battle fought, that would be even better.
I'm sure that the community would soon produce ways to export this data to various number crunching programs, where they could be converted to charts and and graphs. It would also be very useful as a bare bones summary of events for AARs.
The game is epic, and each game seems to have a story to tell. It would be great if there was a tool to help the players tell it!
