i think a WWII game should be real time then a bit like Roma Victor. you are part of an army you get orders you eat and sleep there and you advance. no turn based just real time. when you sleep the screen turns black for a few secs and you wake up again. the tention (sp? must be on every second and you can for once really fight through europe. you can choose factions and players. like

infantry
demolition man
tank commander etc

you can be russian, german, italian english american japanese etc it would have high replayability rate and such but i think it will take some time to create and i doubt it will ever come when im young :S
