Very true, but what's been annoying Oleg is people constantly saying. . .

"But WOP/BOP has much more realistic looking terrain in it!"

As julian265 pointed out, it's really too green and a lot of the naturalness and "realism" are a result of tricks they use to fool the user into believing things look real. Take a photo of the Hurricane and compare it to a real colour photo of it, you'll notice the WOP one looks nothing like the real colours, but it has to be that colour because the rest of the game is so drab and washed out with greens.

Like mazex said, they're using that awful "drab" filter effect from SPR and Band of Brothers.
