Let’s play a game. Name the campaign the image is from.
That’s right. Tunisia, Normandy then Moscow. Very easy to identify as they have unique styles and aesthetics. Very appealing. Now, try and tell which one is Berlin and which one is Stalingrad:
Did you guess Stalingrad then Berlin? What about now?

Did you guess Stalingrad then Berlin? Because you’d be wrong, it’s Berlin then Stalingrad.
If you said Berlin than Stalingrad again, you’d be correct.
The point is, even if you were able to distinguish between the two - do you see how barely recognizable Berlin and Stalingrad are compared to each other? They’re so ridiculously similar. There’s practically no difference between them visually. There’s nothing aesthetically more appealing or pleasing for one over the other.
The reason I’m saying this is to simply say to the developers: No more European city-based campaigns, please. It’d literally just be a Copy and Paste of a mixture of Berlin and Stalingrad so what’s the point? We don’t need 300 campaigns which look the same.
