I'm really mostly interested in seeing how the Civil War turns out. I really hope you modded that. The Southern States seceding from a Southern dominated republic just doesn't make sense to me. I could see Pennsylvania/ New Jersey+ maybe a few Mid Western states voting to join the New England Commonwealth and that would naturally spark a war with the United States, but I don't see any Southern secession being remotely possible. Good luck, I'm really enjoying both the writing and the general plausible sequence of events in this AAR.
The updates are too short though...
Perhaps we could see a Western secession with a Canadian influenced abolitionist leaning California, Oregon and Washington?
