I have been mapping US data into LOGistICAL and have also created the background image. The roads are slowly coming along. It's a big job and I also have to make sure that it will still work fast and effectively in a browser. The game play works fine.
Here's a first screenshot. I haven't set the zoom of each town so is looking pretty cluttered.
If you want to get in first for a play go to logisticalgame.com and try the Australia map. Send me a tweet or support request and I will let you know when the USA is ready for a play.
