Ok, we can pick from any theatre regardless of what is realistic?
In that case: Stalingrad. It would be like we made Stalingrad for FH1 in Forgotten Honor, only like this:
Russians start on the other side of Volga, pretty much like the opening of "Battle of Stalingrad" from FH1 or that level in cod1. Attack on the city followed by the Red Square, city totally bombed out with endless terrain and static debris. Once russians secured the riverfront, tanks spawn and RedSquare attack follows.. Now the map would play similar to bf42 Stalingrad map, until the Red Square (huge one, realistic proportions) are taken by russians. Now tanks stop spawning, and Its infantry shooting in Pavlovs house. After that if the russians break out and push the germans back (hard) tanks come back and its full urban combat again over the entire map. - The most complete Stalingrad map ever made, 1024x2 covering entire map with city structure, harbor, river, pavlovs house, outskirts, factories, streets, red square. Everything.. Oh did I mention, in the RedSquare sequence the snow starts to fall, covering the ground with a snow shader or coders managed to make.
Yep, thats what I want
