Seasons and Weather
Is there any current plan to have seasons and/or weather in the game? I think seasonality in particular could add to the strategic depth of the game. The risk, of course, is that everyone has "boring time" during winter (or months with mud that slow down army movement, etc.), but there are probably ways around that.
What is the desired time scale for the game, anyways? An army can travel a long way in a month or three...
