I would like to see three different graphical explosion models for each type of artillery round fired. Games it seems always has that same graphical explosion over an over in barrages. This would add to the immersion of the incoming rounds.
I would also like to see the ability for the Germans to call in Neberwerfer strikes. I do not recall any games where they have modeled this in.
The Americans could get Naval barrages as well as different caliber artillery barrages.
