Weather. New terrain needs weather. Rain. Ground fog. Snow. And Thunder & Lightening!
and the Dallas Cowboy Cheerleaders too!
I wouldn't mind some fog, I remember there used to be a map that had fog over the ports. That was a good time when you couldn't see jack.
Just remember, HTC does well to be able to keep as many systems as possible to be able to play and the more weather and destructible items in view the more it stresses a system.
