Since i can't sleep coz i am at work my mind was thinking of the old days of travian. I remember i used to download some mod which made the travian town be covered in snow and some actual snowing was going on there. It was such a cozy feeling staying in front of the screen with a cup of cofee and stare at the nice view. So i though this might be a nice adition to the game, to have 4 different seasons (nothing much just some flowers in the spring, some yellow leafes in autumn etc). And if you are to add the weather effects as well....the snowing, some raining, falling leafes etc, that would be something.
Just my two penny worth of thoughts.
