Widelands

Widelands is a free slow-paced real-time strategy video game under the GNU General Public License. "Widelands" takes many ideas from and is quite similar to "The Settlers" and "The Settlers II". It is still a work in progress game, with development still required in graphics and bugfixing. The game runs on several operating systems such as AmigaOS 4, Linux, BSD, Mac OS X, and Windows.
Gameplay.
Widelands has single-player, network and internet multiplayer modes, single player campaign missions and an internationalisation system with translations for British English, Bulgarian, Catalan, Czech, Danish, Dutch, Finnish, French, German, Hungarian, Italian, Japanese, Korean, Low German, Polish, Portuguese, Russian, Scottish Gaelic, Slovak, Spanish and Swedish. Players may select one of four different tribes – the human-like "Empire", the "Barbarians", the "Atlanteans", and the "Frisians".
The game provides four basic tutorials and four tutorial campaigns.
Advanced players can create their own maps with the included map editor. It is also possible to import and play original Settlers II maps.
Development.
Widelands still contains some bugs that need to be fixed until a final (1.0) version will be released, further some wished features, graphics and sounds are still missing. The newest version is Build 21, released on July 18, 2020.
