Well I doubt that the moders can add multiplayer to the game.
Btw how good is "Steel Armor:Blaze of War"?
I know it doesn't cover WW2 but I wonder if mods could do that.
Maybe if the engine is good enough so an expansion would be something that can be considered, it could cover WW2 or any other era that seems appropriate like Korea or even a fictional WW3 as I find the choice of the current theaters very strange.
