Huyana Capac is defined as “Financial” and “Aggressive”
Being “Aggressive” means that you will have a bonus of free promotion (Combat I) for all melee and gunpowder units – making your Quecha, Swordsman, Musketman etc. 10% stronger from the very beginning. This makes even more chance of your Quechas capturing cities in the early stages of the game. Barracks are constructed at double speed – something you would want to build in all your cities as it requires no technology at all. With barracks your units are even stronger (free promotion of your choice). Drydocks are sped up as well, giving you an option to build naval units twice as fast and giving them more experience. Steel should be discovered to take advantage of this building. However, beware – drydocks reduce your city health.
“Financial” should make you research “Banking” as soon as possible, as the Banks are constructed at double speed. As you will probably have many banks it will bring you closer to the Wall Street wonder. Also, you should concentrate on terrains which produce more commerce, as you have a bonus of +1 for each square that generates 2.
