Some of my friends enjoy sending me little reports about the games they play, and occasionally I like to return the favour. Many years ago, I got interested in EU2 because someone sent me a heavily edited game log, and one of my friends still has Civ1 logs from the 1990s. Old World seems well suited for this.
The log itself is both too detailed and not fleshed out enough for this purpose, but it establishes a clear chronology that would help me remember any details I might want to include. The editing to reduce the "PermanentLogList" back to plain text is too messy to do for every Old World game I might want to remember, but I could imagine doing it for a single game that I really want to share, so it's good to know that it's possible. I'm still learning Old World myself, but the stuff that happens is sometimes too good (or crazy) to forget and it's helpful to have a chronology as a context for these memorable events.
