You might have heard about the game Rise of Nations, developed by Big Huge and published by Microsoft. The Lakota and Iroquois are featured in it. The Lakota’s most important bonus is that they don’t build Farms - they gather food by evert villager, scout and infantry unit they have. The Iroquois’ bonuses include their Scouts walk through forests and their own and allied units regenerate heatlh when inside their national borders. The Lakota Unique Unit is Cavalry Archer, and the Iroquois’ one is the Mohawk Spearman.
Why would it be so hard to to this in Age of Empires? Why? It has been done already, by the very same publishing company. So there are some indigenous people who refuse to have their voice recorded? Well, well, well, so the nice detail of units’ speech is hindering the inclusion of one or two civilizations. The Huns have the same in-game dialogue as the Mongols. That’s because nobody knows exactly what language they spoke. The Italians have the same audio files of the Byzantines, and for the life of me I can’t see the reason why, because the developers had no trouble in recording Russian and Hungarian for that DLC.
You need more reading, you are confusing with tours, where the Franks stopped the Arabs in the eighth century, the Turks were stopped by the Habsburgs in the sixteenth century and by the Poles in the seventeenth century (which leaves the timeline of aoe 2, entering fully into that of aoe 3)…
You could make an Iroquois campaign of the Song of Hiawatha and the foundation of the Iroquois confederation (1534-1570) and then another campaign of the Anazasis facing the Spanish expeditions of De Soto and Coronado (1536-1543)…
You can’t put in any civi just because rise of nations did it,all civis needs to be medieval.
Games like civilization rise of nations empire earth all span from the stone age to the information age so you can have Romans Greeks USA Brazil all in one game.aoe is always set in a fixed era so you can’t add faction without any medieval contact with other in-game civis.
The meso civs did not meet the Spaniards until the Renaissance and there they are in the aoe 2 from the conquerors and the Incas from the forgotten,if they do know how to put them well,the Iroquois and the anazasis could fit well in aoe 2…
