First off, great game. I read Brit lives in the Denver area, just my luck, I moved to Kabul from Denver, and get a great designer living in Denver. But the point: Any thought to having Mods for different time periods? Roman, Medevil, etc would be great and enhance some strategies. I have not played enough with the Editor to see if this can be done.
Overall, great game and will pass the time nicely.
