For me the transport strategy is how everything works in coordinated pairs. Transport units move people and goods, though people can move slowly on their own. Your opening ship depends mainly on travel time to Europe but once your scouts start piling up treasure you have to buy a galleon so the king doesn't get half your treasure. The galleon's capacity means you can found a well-equipped colony in one move but meanwhile more treasure is ready to go to Europe so you might make the colony walk a few squares to get the money faster. Wagons go inland to trade but also supply colonies. Which first? And is it better for your privateer to do some supply runs in between lying in wait for rival shipping? Once your scout gets to the west coast and founds a city there you have ships moving in two directions. You also want a road to trade faster with the interior. Guns are an item each colony needs, plus you want to trade guns to the natives living near your rivals, so dragoons transport the guns and wagons take back the surplus horses. Experts and master tradesmen go where they're needed by travelling as scouts or dragoons. There's more detail on city growth and fighting the king in the strategy thread but I find being able to move fast makes everything easier. The transport strategy is finding the most effective way to manage horses, wagons, ships and roads.
