You know, it occurs to me that this theme could end up being bad for performance and clarity because a proper jungle is so full of trees and smaller plants. The game started out making use of mostly desert environments because deserts are so empty aside from whatever buildings you put in them. Just rocks and cacti here and there. And even in the alpine theme, you just had clusters of pine trees outside the field of play, which are rendered as just piles of cones. Granted, they could just end up making it really sparse so it only barely reads as a jungle, or go for some narrative where RED and BLU have been clear-cutting the rain forest because that's the kind of companies they are.
