The Anno series has always involved setting up production chains for various resources, in order to maintain a steady flow across your settlements. The latest entry in the series is no different, Anno 1800 production chains being at the core of its city building experience.
Here's how Anno 1800 production chains work.
Anno 1800 Production Chains
Anno 1800 production chains work very similarly to how their counterparts in previous entries functioned. Things start off simple with chains involving two buildings. One of them produces the raw resource, while the other refines the resource into goods that can be used by your population. To exemplify, the Work Clothes production chain requires Sheep Farms for wool, which is then turned into Work Clothes, needed by both Farmers and Workers, at the Framework Knitters'.
Anno 1800 production chains become more complex as you progress through its population tiers. Later on, you'll find refinement buildings that require a constant feed of two raw resources in order to function. Sewing Machines, required by Artisans, are made at the Sewing Machine Factory from Wood and Steel. Steel itself requires Iron and Coal in order to be produced.
You also need to take into account the fact that some Anno 1800 production chains require resources that cannot be cultivated or produced in your region. Sugar Cane, required for Rum, can only be harvested in the New World, just like you'll be hard pressed to find Iron or make Windows in the New World. Thus, you'll have to set up trade routes, or manually supply your production chains as you move towards the end game.
