Widelands is a free, open source real-time strategy game with singleplayer campaigns and a multiplayer mode.

In Widelands, you are the regent of a small clan. You start out with nothing but your headquarters, where all your resources are stored. In the course of the game, you will build an ever growing settlement. Every member of your clan will do his or her part to produce more resources - wood, food, iron, gold and more - to further this growth. The economic network is complex and different in the five tribes (Barbarians, Empire, Atlanteans, Frisians and Amazons).
