For spain the easiest way to win is to reapeatthis build:
-16 villager age up (3 vill card)(outpost+gold politician)
-Build a trading post during transit
-ship 700 gold upon colonial
-ship 700 wood
-go to age 3 (4 hussar politician)
-make barracks and houses with wood
-make skirm from barracks and ship in rod/falc/lance as support
For ottos you can go:
-normal age up (trading post and 3 villager card)(outpost+ gold politician)
-ship 700 gold upon age up
-ship 700 wood
-go to age 3 with 4 abus gun/4 hussar politician
-make barracks and houses with wood
-Make jans from barracks with abus/falc/huss/mameluke shipments
If you want to play well you can also trading post or schooner boom.
For those you will have to adapt to how aggressive your opponent is being so that you can boom as hard as you can without dieing. So I really can't give you a build order for those.
