Ok, I've tried a little (alone), so I can't judge the gameplay yet, only the looks.
I've already mentioned the look of the church, but there is also this graveyard. I somehow doubt that in the capital there would be graveyard right in the backyard of some house.
I liked those trolleybuses, they look good, but you should consider adding wires above them.
I've came across some interesting poster, which says "We will come to Berlin".
In Kommisarhaus there is german ammo box for MG42 (???). Near it there are few green spots on the floor and the ceiling. Probably lighting bug?
Destroyed Tiger and SU-122 in the city?..
And the monument looks EXTREMELY cheesy. If I were you, I would delete it and put a horse from Warsaw or anything.. Minumap is also looks meh to me..
From what I've seen that is definetly not Moscow, but if it has good gameplay, I will not have problem with it.
