I think that would be cool but it will never happen. One time there was a desert map in the MA and people FLIPPED THE F OUT! All because of the color of the terrain. People would say that the color was actually causing them physical pain, I'm not kidding. And numbers dropped when ever that terrain was in the MA so it was taken out of rotation. I may be mistaken but I think they just changed the terrain textures to green and put it back in rotation. Never underestimate the democratic power of stupidity.
Wrong on several counts.
A few people did complain that the coloring gave them headaches, I think it was more the game play
People did NOT "flip out" as it was a pretty popular map as it had these huge unrealistic canyons which made for great air combat. It also had lots of GV bases around the outside edge of the map where GVers could play pretty much unmolested from the air. With wide water ways splitting the map it made for lots of CV to land battles.
I don't remember the "numbers dropping" when the map rolled around in rotation, as I said it was a popular map. It was taken out of rotation because HTC did an update to the terrain and the master files for the AKDesert map were lost so it could not be updated.
NHawk did make a new map called SmPizza which had the same basic shape but didn't have the water ways nor a sand/desert texture.
So it wasn't an issue with the "players" as posted, it was a technical issue.
As to getting a winter map, email HTC and ask if they would accept one and then get to work making it. I don't see where it would be as big an issue as it use to be. File size was a big issue due to transfer/download times, but with the vast majority being on high speed internet I don't think it would be as big an issue. The problem with a winter map or a desert map is the number of tiles that would have to be reworked increasing the size of the download. You'll never know with out asking tho.
