The Mapuche are really nothing similar to the Pueblo. If you wanted a South American civ similar to the Pueblo/Anasazi, look to the Chachapoya [Cliff side Mausoleums, large city confederation, massive trading and tributary confederation that traded goods from Panama, to the Amazons, to possibly Polynesia, and to the rest of South America, one of the most important religious centers of the Pre-Colombian World, helped the Spaniards destroy the Inca, the most massive Pre-Colombian city in all of South America by mass and size, etc.] The Mapuche are "The Sioux of the South" for a reason and Lautaro wasn't successful in expelling the Spaniards unlike the Pueblo. They are another cavalry civ - And considering the developer's western upbringing, it would make sense for them to look at the many cavalry civs here in N. America prior to the Mapuche. Pueblo and the Mapuche is like comparing apples and... well cantaloupes.
