Have we done any hypothetical scenarios? I don't recall any but...my memory is....not so much.
Be neat to try a 'what if'. What if Russia didn't stop at Berlin and the allies were forced to fight off the communist horde. Could maybe even use the BoB map to do it. Just change the German bases with German planes to Russian planes.
US/UK vs USSR all late war rides....maybe even bring in the Italians on the allies side.
Dunno if it's a great idea, but would be interesting. (I love the Yaks)
