Cool; glad you liked it. That'll be great to see how the stars do playing during World War Two, too. (And FDR would simply have to tell Landis not only to keep playing but thta he's insisting the players stay on the field to provide for better morale at home.) This is a great universe you've created. And, you're right - what-iffing is really about how the world could be, and I think everyone enjoys creating timelines about how they'd like the world to be.
Do you ever discuss alternte history in class? I would imagine high school students would be able to do it, at least advanced ones. One of my only regrets in high school was that when I had an extra period tht I used it for study hall instead of something I had a chance as an AP student to do. I thought later tht it would have been really fun to do an AP History Independent Study analyzing what would have happened had Kennedy not been shot, or the '48 or '60 or some election gone differently, and done it as a text down tot he present (1987 at that point). I did go to a college where I.S. was a senior requirement (College of Wooster), and though my major it was in was Communication, I found that lots of fun!
I have a few timelines that I started or expanded from what others had done on
