I would not recommend classic mode any more unless its just for offline play. For any of the new terrains since 2006 classic mode has not been supported and all the textures will be very dark and ugly. Like playing over iwo jima.
I really would like to try a terrain that would not have textures just solid colours. Make it look like Ravenfield, Ancient Warfare 3, Unturned, Rise of Liberty all the new games that are going so retro. Would make WBs look less dated but retro
The actual game mechanics, FMs and game play would be what matters not eye candy. This could be the new classic retro
