The campaign is a slowly-unfolding tutorial, yes.
I'm only a beginner to 1404 myself, but the basic progression of gameplay is that you build houses to increase your population as much as possible. Hitting milestones unlocks new buildings and new civilization levels - social classes who demand certain resources to remain happy. You generate those resources by building plants and connecting them to a warehouse via roads, which sends out carts to collect your fresh goods.
Your colony starts off as Peasants who only require Food, Drink, Community, and Faith. Food and Drink can be satisfied by fishing huts and cider farms, Community by connecting Peasant houses to a Marketplace, and Faith by living inside the glowing area of a nearby Chapel. You'll need lumberjack's huts to provide your own supply of Wood for building, as well as money, which is generated by the taxes you charge your people.
Pretty soon you'll unlock the Citizen class, and your Peasants will start ascending classes if you keep them happy and reduce their taxes to DARK GREEN for a short period. Their houses will change appearance one-by-one to reflect this. Citizens now require Spices in their Food, Amusement from a nearby Tavern, and also Clothing, which is satisfied by Linen shirts.
Linen is your first intro to production chains, where the resources produced by one building are "picked up" by another building, to create its own resource. You'll realise that each weaver's hut you build needs 2 hemp plantations to keep it running at maximum efficiency. Balancing your production chains is literally the key to being successful in this game, so don't be afraid to google the ratios.
Spices, on the other hand, must be obtained by trading with Oriental islands, and that opens up a whole new aspect of gameplay that you can discover for yourself :)
