Is it realistic to assume that USSR had a strogner economic value than what the starting map shows? I heard somehwere that the two biggest allied powers were USA and USSR, or was that an foolish source of info?
Assuming you mean historically, well, Russia basically threw a ton of unarmed men at Germany. So they spent and lost the most men. But not really for great return. It depends on how you want to interpiet that. But, also, Russia was economically a mess. Corupt communism and all.
Anyway, I like the minefield idea a whole lot.
