Maybe an essay summarizing a book about an ATL event? Like in my TL I have a major war in the 1560s, and I could write a summary of a book discussing the war. Perhaps with the added caveat of the summary has to be at a C level, since not a lot of people can easily write at the average level on purposeAnyone have any good ideas? I'm stuck now...
One of my ideas is making a future of your timeline snapshot if you have one? (But that would make it harder for people who never had one)
