Second try...sorry

1) Walls with height. I know in WinSPWW2 you can use hedges as a replacement, placing some on top of each other to gain height, but I don't see any such option in SPMBT. The eye candy and gameplay would be tremendous.

In the map editor you can set a hex height to whatever you want. Combine that with a tramway or something that looks like a wall and you're good to go.
