Despite the same name the game from Winning Moves is not a new edition from this game but a new game by Harald Lieske.
In short: It is a game in which the players try to bring their 9 pieces to the opposite side of the board into their own areas. The board is made up of different terraintypes which are passable or impassable depending on the weather conditions. The players are able to influence the weather by using weathermarkers.
Sorry for everyone still looking for Wind Und Wetter by Jumbo. And no I am not selling my copy.
