Imagine those graphics with high resolution so they look like drawn comic book art. No pixelated edges but no dated realism either.
The retro movement in games especially by Indie developers is pretty big right now. Even if you look at War Thunder the graphics are awesome but flying in a large map you start to see its limitations too. Unless you have a killer rig the trees and ground objects come on like our clutter in WBs and seem to pop into place which I find hurts immersion. If you look at WW2 Online its graphics are even more dated than WBs but the mechanics and design behind it is excellent. Updating the graphics is a huge issue with the game and they are trying to bring up an old game engine to speed which I think sometimes you cant and have to start again from scratch. I wonder if WBs is at the same point. Some more eye candy with lighting and such but the general terrains, planes and cockpits are stuck without much change until they are rebuilt from the ground up on a new engine.
When I build terrains I sometimes misname textures and just have black space where they are supposed to be. It doesnt look real but you can see every fold and crease in the terrain and follow them easily. There is more detail behind the textures than with the textures. That being said you would have to apply some basic colours and such which I would need to experiment with but I am sure its possible.
Just an idea but like most games I am sure you could have a player mod. Retro WarBirds coming to a screen near you.
