Boring as Russia?
I think Kuban is a beautiful map. If they go further west a bit, the Crimea area should also be a jewel to fly on.
The Moscow and Stalingrad maps may be boring to you, they are not to me. A lot of the air war going on was on Russian soil, so that justifies any map in Russia, for there was fighting all over the place there (and it went eastward and the back to the west, so multiple uses for the same map).
I do not find Russia boring at all. In fact, I knew very little of the war in Russia until I forced myself to learn some more about it, simply because I was flying this sim.
No, not boring (for me).
