The Settlers III: Gold Edition

The Settlers III is a real-time strategy, isometric city-building game being the second sequel to The Settlers, making it the third game in The Settlers series.
The most notable difference between this game and its two predecessors is that there are no more roads - all units, including carriers with goods, can walk around freely. This simplifies the building of a settlement, since only the distances between buildings are relevant, and not how roads can be constructed between them. Military units are now directly controlled, making fighting more similar to games like Command & Conquer or Age of Empires, than to the previous Settlers games.
