Very creative work. I'm assuming the tossing of the NY owner will be the precursor for the birth of a rival American Association clone (I can't say it'll be the AA because your world isn't a true copy of the real one, but a slightly altered version).
It does beg the question: how much time are you spending in creative writing versus actually playing the game?
Of course, reporting a history takes more time than actually coming up with the results to report on, but you seem to be taking a lot of effort to construct storylines and arcs that proceed in the background of the game, particularly since I'm pretty sure there's no real-life information available to base these characters on.
At this rate, it'll take you a while to get to your post-WWII world.
