I like trade tech as well by why is TRADE2 specifically so important, other than it leads to trade3.Originally posted by chilliwilli
Trade lvl 2 is the most important advance for the Incas once Spain comes knocking you will have tps and colonies everywhere. A few state gifts will stop Spain from taking them and eventually you will be in position for an alliance. Investing in naval is pointless as the incas by the way. Discovering a few bodies of water is not worth it and when you go to war with a A european nation your outdated navy will only help you lose percentage points. You are better off building infantry/cavalry and garrisoning your provs only going on offensive when you know you can win.
Why as the Inca would you build TP's, you want colonies.
Also naval tech will help when you want to get that army to Europe without losing them all to attrition.
