I guess I didn't understand what Hitech was saying. We already have a winter terrset in the game, and I thought he was saying that someone would need to compile (legal?) winter skins and send them in to be included directly into the (existing winter?) terrset.
I thought he meant it would be the official method instead of a builder adding them to a single use terrain, but it seems I'm the only one thinking that. If I'm right, it begs the question of which skins, and if both vehicles AND planes are required. I can see the need for winter skins on all GVs, the C47 and Fi156, and maybe the Stuka, but after that...?
