The game has rainy weather which is visualised with actual rain, but terrain doesn't change with weather.
Ok. I was thinking of the muddy/snow covered terrain from PG/PzC. It was sorta disconcerting in PzC when the terrain was white in game and the mini map next to it still green. I suppose on your nice 3d map it will be sufficient to show the rain falling instead of recoloring the ground.
And no snow in the Pacific [:)] Something for a Sino-Jap or Soviet-Jap war expansion perhaps.
And North America, a possibility that you`ve already mentioned. Speaking of which, if you do implement snow eventually, I hope you will consider some transition between snow and dry terrain. It has been mentioned by fans for PzC, where you could have frozen turning into dry the next turn. Should be some sort of muddy terrain transition between them.
