Yrri always wondered why pro versions of snowy maps didnt use the badlands theme, it looks so much more interesting than alpine dirt, and the shit that was buried in snow before doesn't look so weird when its buried in sand instead of dirt
I always figured it was for that "thawed out" look and so you wouldn't have to change many props. You can keep the rocks the same grey color, and you don't have to get rid of any of the trees. I would wager it also means people have to do less work to the skybox as well. I think people also just think Alpine is prettier than Badlands. You would know more than me though, I'm not a mapper.
I think Coldfront and Viaduct would look odd with the Badlands theme. I think Barnblitz and Snowycoast might actually look better, but I also just hate playing them either way, "pro version" or not.
