Playing the campaigns is amazing... I have been fortunate enough to have the game running well.. and the campaign missions are cool.. but man did they load a LOT of objects on the map... its like they just populated the whole BoB map!
I think many people would have a better experience with less cluttered maps in terms of ground objects and trains/cars/trucks etc. If it was a dynamic campaign, then those objects would be vital..but it might be easier for lower end PC's if a more sclalable campaign was available..
Knowing the IL2 community, I'm sure there will be a DCG generator fo some kind coming along shortly
