Incas (Age of Empires II)/Strategy

Strengths
Incas is a very versatile civilization, their housing bonus can be very usefull for increase your population quick  or for saving some wood, their stone cost bonus and the villager bonus from blacksmith can be very usefull for make strong defenses and fortificate your city or for making a tower rush very quick, their extra llama bonus can be use for exploring in early game or just for taking some extra food.

Incas Unique units are both a very powerfull counterunits. The Kamayuk is the only melee unit of the game that have range (+1), this means that if you have two or more lines of kamayuks  the second line also attacks giving them a group bonus (with two lines of melee units attacking the frontline of the opponents) they can also attack behind the walls, the anticavalry bonus of the kamayuks is very helpfull in late game, they could be very powerfull if you can mass them, they are much better than a regular halberdier. The slinger in other hand is a anti-infantry unit, in some way similar to a hand cannoneer but weaker and cheaper. Both unique units and the eagle warriors movement can be improved with the unique technology "courieurs" that gives them 10% extra speed, this unique technology plus squires (+10% speed for infantry) increases considerably the speed of eagle warriors (both technologies make 20%) so incan eagle warriors can be very usefull on a raid (remember eagle warriors are indeed a very quick infantry)

Their team bonus makes their allies to build farms quick, this lets the team to gather food more efficiently.

Weaknesses
Like the other Meso- American civs, the Incas' total lack of cavalry or gunpowder puts them at a disadvantage in the late game. While Eagle Warriors make decent cavalry substitutes in the Castle Age and early Imperial Age, they don't have a lot of HP so are easily outmatched by Paladins and they cost a lot of gold, unlike Hussars. So in late game they must rely almost entirely in their  unique units and other counterunits like skirmishers and halberdiers to attack or defend in lategame ( and these counterunits are not very strong if you can't mass them)

In a frontal attack Incas are not very powerfull, beside the advantages of their unique units  these doesn't have  too much HP or armor so is better for them to take advantage of the map an make several fortifications in medium and late game.
