I play World of Tanks and the building in this game are awesome. If some of you creators would like some ideals give it a look. I would love to see some of these in our routes.
The game is WWII era tank battles and it's free to play. Download and look at the scenery.

I don't know what the game engine was that they used to make this with but it looks a lot like a trains sim program.
