Not at all a fan of the 700 player start and the hyper inflated demand that comes with it. This type of start completely ruins the first 50 years of the game.
I tend to understand what you mean, but at the same time, without the increased demand in the 50s, USSR would have been unplayable, even for one player.
When last GW#2 started, with increased demand, most routes from Moscow had ~30 demand. Add this to the range needed in USSR, and with your setting I can replace my DC-3 with a Heron. In Moscow.
And other places would probably have the same problem.
