The Battle of Polytopia, formerly known as Super Tribes, is a turn-based world-building strategy game developed by Midjiwan AB. The player leads one of fifteen Tribes to conquer a square-shaped world by capturing Cities. Cities earn Stars that can be used to research Technologies, train Units to engage in Combat, and develop the surrounding Terrain to gain Population. Be warned, however: the more Cities that are added to the empire, the higher the cost of technological research... and the greater the area that must be protected from the endless onslaught of the other tribes!
