The Great Plains is a map in Age of Empires III.
Every player and even the Trade Route is shoved off to the southeastern side of the map, creating large plains to the northwest with several Native settlements and much expansion room. Because of the map being open, there are almost no choke points. Players should pay attention to the Natives, as they are very useful on this map.
The landscape of the plains allows many herds of animals to wander the map, but only hosts scattered patches of wood. There are a few mines to gather from, but they run out quickly; the Natives only cost food and wood, which can be used to the player's advantage. Because of the resources scattering the map, players should expect to send villagers out into the wilderness to find more coin or wood.
The Great Plains are a broad, grassy, sloping expanse of prairie land that extends from Texas in the south to the Canadian provinces of Alberta, Saskatchewan, and Manitoba in the north. The climate is semi-arid and the dominant vegetation of the region is a large variety of tall and short grasses. Trees and woody plants tend to grow only along streams and rivers. The area was once home to millions of bison (and dozens of Native American tribes who followed and relied on the herds) that were systematically hunted to near extinction for their hides and tongues. The bison were gone, and the Native Americans were forcibly removed to reservations or driven away.
The Homestead Act of 1862 promised 160 acres to anyone who could settle and live on their claim for five years. Settlers had to be 21 years old, the head of a family, or a citizen (or in the process of filing for citizenship). The arid region wasn't especially suited to farming and the going was rough for many homesteaders. Those immigrants who came from the grassy steppes of eastern Europe and western Russia fared better than others, but many faced such hardships that they gave up their claims and returned east.
